Technical Specification for the HSR 49.2 MHz RF System Power Amplifiers

SCOPE

This document defines the technical specifications for the Hadron Storage Ring (HSR) 49.2 MHz Radiofrequency (RF) System Power Amplifiers to be used at the Electron-Ion Collider (EIC) at Brookhaven National Laboratory (BNL) managed by Brookhaven Science Associates (BSA).

Background The EIC Project will design, build, and install the accelerator hardware for a new electron storage ring, an electron injector, and modifications to the hadron ring required to produce an electron-ion collider and infrastructure. It will include one interaction region, with an allowance for a second, and one detector. The facility is designed to meet requirements to ensure high reliability and availability for the user program.

The High-Power RF (HPRF) System for the HSR 49.2 MHz RF will be used to provide power to the 49.2 MHz Normal Conducting RF (NCRF) Cavities. These cavities will be used for the bunch splitting of hadron beams in the HSR of the EIC. Amplifiers that can reliably deliver up to 120 kW of RF power are needed to achieve the necessary bunch splitting pattern in the HSR 49.2 MHz Normal Conducting RF Cavities.

Definitions Local Protection – Protection designed to be applied at the Solid-State Power Amplifier level.

Solid-State Power Amplifier (SSPA) – The Solid-State Power Amplifier (SSPA) comprises all subsystems (AC distribution, DC power supplies, RF, cooling, control) assembled in a functional device that provides RF power amplification. This term is mutually exchangeable with HSR 49.2 MHz RF System Power Amplifier for this document.

Amplifying Stage – An Amplifying Stage is defined as the group of identical RF amplifiers that are operated in parallel to provide signal amplification within the SSPA. A SSPA usually has at least a couple amplifying stages.

RF Device – A RF Device is a RF power field-effect transistor (FET). It usually has one or two sets of gate and drain terminals, a metallic flange that is also its source terminal, and either a plastic or ceramic package covering its semiconductor elements.

Radiofrequency Power Amplifier (RF-PA) – A Radiofrequency Power Amplifier (RF-PA) is defined as the modular unit of the last Amplifying Stage within the SSPA. It may have one to several identical RF Devices operating in parallel with embedded RF splitting and combining structures. A SSPA may have up to several hundred RF-PAs.

Remote Control – The Remote Control system is BSA’s control system to handle communication between different equipment. It will be implemented via Experimental Physics and Industrial Control System (EPICS).

Soft Limit – An adjustable limit to a fault or warning condition which may be further sensitized by the end user.

Hard Limit – A limit to a fault or warning condition that is locked behind contractor-protected password, meant for critical SSPA protection.

APPLICABLE DOCUMENTS

The following specifications, standards and drawings form a part of this specification to the extent specified herein.

Stability The RF Amplifier system shall be unconditionally stable over the entire load space and dynamic range.

Forward Power Degradation versus Load VSWR Up to 3:1 Load VSWR, the SSPA shall output 100% of its nominal power. For higher values, the SSPA must present a fault and a transition from the RF ON machine state. The SSPA shall not be damaged in the event of a short or open circuit on the RF output.

Input Overdrive Protection There shall be hardware within the RF amplifier system for input overdrive protection. The hardware shall limit the RF power at the input of the system and the RF amplifier system shall not be inhibited.

Burn-in Testing The SSPA shall go through a 48-hour Burn-in Test at full rated power at the Contractor’s site, without any faults, warnings, trips, or failures.

Redundant Operation The SSPA must be able to provide 120 kW output power with up to 10% of all RF-PAs either in a failed or inhibited state. If a RF-PA fails or is inhibited during operation at any power level, the SSPA must be able to withstand a sudden change in input power that will try to compensate for the failed/inhibited RF-PA power loss in order to restore the rf output power to its previous level before the failure or inhibit.

The SSPA must be able to provide 120 kW output power with up to 10% of all RF-PAs either in a failed or inhibited state for an indefinite amount of time with no negative impact on the expected lifetime of any of its components due to sub-optimal operation conditions. If more than 10% of RF-PAs fail, the SSPA can continue operating if it is deemed safe to do so, and if it does not exceed any of the Soft or Hard Limits for the SSPA.

Apart from the redundant operation described for the RF-PAs above, the SSPA shall not have single points of failure in any of its Amplifying Stages, i.e. the SSPA must remain operational even if at least one unit of any of its Amplifying Stages fails or is inhibited.

Power supplies The Contractor can select power supplies so long as the SSPA characteristics comply with the requirements as specified herein. Redundancy shall exist. Like the RF-PA devices, the selected power supplies must be modular, i.e. several units must together provide the necessary total DC power to the RF-PA devices. A single failure shall not inhibit the entire SSPA. It is of the utmost importance to have a design which is reliable, requires minimal maintenance, and enables easy replacement of faulty modules/components. The controls shall operate on BSA supplied 120 VAC. The main power supplies shall operate on BSA supplied 480 VAC 3-Phase. The 480 VAC 3-Phase will be 4 wires plus GND. The SSPA shall be protected against damage if the AC voltage is out of range.

Earth Connections

Chassis Earth Connections A threaded ¼”-20 earth bolt shall be provided on the rear of each chassis within the racks. Each chassis shall have its own earth ground cable connected to the rack.

Rack Earth Connections A threaded ¼”-20 earth bolt shall be provided on the top of each rack.

Control System 120 VAC Switch An on/off switch for the 1-Phase 120 VAC supply that powers the Control System and a circuit breaker must be present inside the Control System Rack.

Internal Energy Dissipation In the event of an interlock or command that forces the SSPA into a lower machine state (see Section 3.2.11), the SSPA must be able to discharge all of its stored thermal and electrical energy in a safe and controlled manner. Access to the interior of the SSPA shall not be granted unless there is evidence that energy from the AC and DC systems are within safe thresholds.

SSPA Reliability (MTBF) The SSPA shall have a predicted MTBF of greater than 10,000 hours in an environment subject to all possible combinations of values defined in Table 2. The units of all Amplifying Stages shall have a predicted MTBF greater than 35,000 hours.

Temperature Limits

Temperature Limits on Exposed Surfaces The temperature on any touchable surface shall be less than 48.89 °C (120 °F). A touchable surface is defined as any surface that can be accessed without the use of tools.

RF Device Die Temperature The maximum die temperature of LDMOS RF Devices shall not exceed 160 °C over the entire load space, dynamic range, and range of environmental conditions. Gallium Nitride (GaN) RF Devices die temperature shall not exceed 180 °C over the same circumstances outlined above.

RF Hardware Requirements

RF Switch

There shall be a high-speed RF switch at the input of the SSPA that shall shunt the input RF to a 50 ohms termination when the SSPA is not in the RF ON state. The purpose of this switch is to quickly terminate the input RF signal in the event of a fault condition. The rise/fall time of the RF Switch shall be between 100 ns and 500 ns.

Thermal Protection Temperature sensing shall be fitted to heat-generating devices in the SSPA to provide equipment protection if internal temperatures exceed allowable limits.

Water Cooling Water cooling will be provided by BSA. The SSPA shall incorporate water cooling to ensure that the components within the SSPA stay within their thermal limits. A minimum of 80% of the heat generated by the SSPA shall be removed by water cooling. The water shall exit through a flow meter for each water-cooled rack. There shall be a drain valve at the bottom of each rack to drain the water. The cooling system shall be designed such that very little water remains trapped after draining. The cooling system shall tolerate input cooling water with an input pressure of at least 150 psi (as per Table 2). The cooling system total pressure drop shall be no greater than 40 psi. Required flow rates (maximum, minimum, nominal) for operation shall be defined by the Contractor.

Air Cooling In addition to water cooling, the SSPA may incorporate air cooling to dissipate up to 20% of the total heat generated. If required, air shall be drawn in through vents at the front of the chassis and expelled at the rear of the chassis. Air filters shall be fitted to any required fans. Fans and air filters shall be affixed in such a way that they can be easily replaced without the need to remove chassis from the racks.

· RF ON

The state machine state must be always indicated visually by a 4-tier tower light (green, yellow/orange, red, and white) mounted on top of the SSPA. The white LED must be turned ON if the SSPA has a warning or fault. The description for each one of these states is defined in the following sections.

AC OFF state In the AC OFF state, the SSPA control system shall be operational, and the AC distribution system shall be disabled through the AC Contactor switch. All the fans present in the AC distribution system must be turned off. This state must be visually represented by a flashing red light. A transition to and from this state will follow the AC Contactor Actuation logic described in Section 3.2.7.

AC ON state In the AC ON state, the SSPA control system must be operational, the AC distribution system shall be enabled through the AC Contactor switch. The DC power supplies must be disabled, and the RF Switch must be open, i.e., connected to a 50 ohms termination. The assigned color for this state is green. In this state, the following conditions must be met:

RF ON

In the RF ON state, all the conditions mentioned in the DC ON state must be met, and the RF Switch is closed. The RF Switch can only be closed from the DC ON state, and all external interlocks concerning the machine operation must be cleared. Any internal or external interlocks will trigger transitions to either AC OFF, AC ON or DC ON states, depending on which respective interlock were triggered.

LED Status Indicators In addition to the 4-tier tower light described in Section 3.2.11, the status of the SSPA shall be indicated locally by a LED array on the front of the Control System rack. The LEDs shall indicate important aspects of the operating status, fault/warning status and control signal status. In general, a simple color code shall apply, whereby a white LED indicates a fault/warning condition, and a green LED indicates a normal condition. The machine status LED colors and behavior should follow that of the 4-tier tower light, that is:

· Red for RF ON.

· Yellow/orange for DC ON.

· Green for AC ON.
