Amendment 01 The following Addendum 01 is being issued for the subject Request for Quotation: 348965_Pumps Extension to this SAM.Gov posting will be granted and final submission for bids will be end of day 9/18/2024 Answer to questions in red. Pump must be bakeable up to 550 deg C for 500 hours min. Need clarification of this specification. SLAC Requirement so that unit can be rebaked multiple times. Pump indicated current must not exceed .25 micro amps after a stabilization period while connected to 5.5 kV power supply.

[AGILENT]: Does this specification apply to an ion pump open to the system or close off on itself? Can you confirm the power supply make? Clarified on the drawing SC-700-866-40 Rev 2 All stainless steel components which form the vacuum envelope must be made of 316L. would like to get clarification on specification requirements to Line 3,4, and 5, as there is a range of steels types listed. All otherwise unspecified components must be 316L 2.75” CF must be made of 304L VAR or ESR.

[AGILENT]: Same question as in line #5. Must be 304L .25” dia must be 304L or 316L.

[AGILENT]: Same question as in line #5. must be 304L or 316L Pumps must be processed at 450 deg C for min 16 hours and conform to drawing specs. Need clarification. Typical processing is performed at 450 deg C but typically processing time is based on pressure of the ion pump during manufacturing. SLAC Requirement for processing All components inside vacuum envelope must be vacuum degassed at 1000 deg C for min of 30 minutes. Need clarification this differs from standard manufacturing process.

SLAC requirements for processing Ceramics should be cleaned and air fired at 1000 deg C. [AGILENT]: Need clarification. Drawing SC-700-866-40 Rev 2 may help clarify Must meet specifications outlined in drawing SC-700-866-40 Rev 2. Can SLAC clarify the requirement leak rate, the document attached this specification was unreadable even at magnification.
