Princeton Gamma-Tech (PGT, now Thermo Scientific).  Unfortunatley, their x-ray division was liquidated per the official note on their website:

"X-Ray and Nuclear products have been discontinued and no longer offered for sale by Thermo Fisher Scientific. For Service and Support...Thermo Fisher Scientific has entered into an agreement with Berkeley Nucleonics Corporation (BNC) to provide warranty and non-warranty support for X-Ray and Nuclear products"

However, BNC documents seem to pitch it as part of their company and I've seen "BNC Princeton Division" mentioned (ex: [Nuclear presentation]).

===== JM unit =====

{{jm:pgt:prism:overview.jpg?300}}

This unit was bought for reasonably low cost with hope to learn about them and maybe fix it.  Worst case, this unit should work under atmosphere or scrap for the dewar

[{{:ebay:solanotraders:ls30148_191140107113:2.jpg?200|Source: eBay 191140107113}}]

This unit appears to have ConFlat connections and a fixed angle detector.  Has the same sort of preamp seen on other models


====== JT Cool ======

[{{:pgt:npc:jt_cool_2.jpg?300|Source: NPC}}]

Small crycooler to replace the LN2.  Requires Model 483 Controller (white box thing).

Summary [NPC]:
  * Uses "propreitary refridgerant mixture" (He?).  CFC free
  * Claims 5 years of maintenance free operation
  * Supports up to 50 foot gas lines
  * "Retrofit available for existing detectors, including those of other manufacturers"
  * 10-35C environment
  * Down to 70K
  * Copper gas line option

[{{:ebay:solanotraders:imagemaster_400720324518:back.jpg?200|Source: eBay 400720324518}}]

They had a LS30148 and a PRISM 60 for sale along with it, unclear if they somehow go together.
