About this file
This document is a technical CAD drawing for a heater chamber assembly, likely for an ion gauge calibration service at the National Institute of Standards and Technology (NIST). The detailed technical drawing specifies precise design requirements for a hexagonal-shaped enclosure mounted on a table, including critical specifications such as:
Key design constraints include: a 51.00 mm height, 22.00 mm radius, and 100-degree configuration; a red-shaded "keep-out volume" where no components can protrude; requirement for internal 2-inch maranite insulation with unblocked table holes; mandatory placement of pneumatic valve actuators outside the heater enclosure; and provisions for routine access by removing or opening side panels without full enclosure disassembly. The drawing also specifies that port holes for valve actuators must have removable insulated covers, and the enclosure must be installable with pneumatic valves already attached to the chamber.

1.
Table has internal 2 in maranite insulation.
Holes in table must not be blocked.
Actuator section of pneumatic valves must be outside heater enclosure.
R22.00
17.00
100° R28.13
Red shaded region indicates minimum keep-out volume.
Heater enclosure and frame must rest on table.
Routine access without enclosure disassembly by removing or opening side panels is required.
Potential frame and/or enclosure shape (other shapes are acceptable, see requirements).
Port holes to accommodate valve actuators must have removable insulated covers.
Enclosure components cannot protrude into the keep-out volume.
Enclosure must be installable with pneumatic valves attached to chamber and pneumatics must be removable without full disassembly of enclosure.
