[Pansophy] FW: SNSPPU - 8 Pin Cryogenic Feedthru

[Peter Owen]

If they pass electrical check and leak test after cold shock, I don't think the feedthroughs need another inspection procedure. Please let me know if you think the additional inspection is still necessary.

To recap, the feedthroughs still go through

  *   SNSPPU-ELEC-FT08P-CHK
  *   SNSPPU-VTA-CSHK-FT08P
  *   SNSPPU-CMA-FT08P-LEAK before and after coldshock

Peter

Hi Gary and Anne,



I've asked pansophy group to remove this traveler, SNSPPU-INSP-FT08P. The steps in it are covered in other inspection travelers so this isn't needed.



Thanks,

Peter

Peter,

Is it your traveler that Anne is talking about?

My feedthroughs are installed on end cans. They don't see cryogenic temperature.

Dwg in the traveler does not appear to be a link – however there is a picture of the drawing on Page 1, assume that’s all I need
