About this file
This document is a Criteria and Description for a Mobile Leak Detector required by the SLAC National Accelerator Laboratory, which is operated by Stanford University for the Department of Energy.
The key requirements for the Mobile Leak Detector are: a minimum detectable leak rate of 1x10-12 mbarl/s for helium in vacuum leak detection mode and 1x10-8 mbarl/s for helium in sniffer leak detection mode; a response time of 1 second; a helium pumping speed of 10 l/s or higher; a backing pump capacity of 35 m3/h or higher; and a dry, oil-free pump. The award will be made based on the Lowest Price Technically Acceptable method. Offerors must be registered in the System for Award Management (SAM) and the resulting purchase order will be subject to SLAC's Terms and Conditions for Fixed Price Commercial Supplies and Services.

Quantity 1, Mobile Leak Detector Must meet the following criteria.
Criteria Description
a. Minimum detectable leak rate for Helium (vacuum leak detection)
b. Minimum detectable leak rate for Helium (sniffer leak detection)
c. Response Time
d. Helium pimping speed
e. Backing pump capacity
f. Backing pump type
The sensitivity of the leak detector is of the utmost importance. The minimum detectable leak rate for helium in the vacuum leak detection mode should reach 1x10-12 mbar∙l/s.
The minimum detectable leak rate for helium in the sni er leak detection mode should be better than ≤ 1x10-8 mbar∙l/s
For accurate identification of exact leak location, a fast response time of 1 s is required.
For maximum leak detection e iciency, a helium pumping speed of 10 l/s or higher is preferred to minimize the recovery time between leak detecting events.
To reduce the initial pumping down time, a backing pump capacity of 35 m3/h or higher is desired.
A dry pump (i.e., oil free) is required to eliminate the risk of contaminating the ultrahigh vacuum systems.
