Title:
CRYOPUMP
Document Type and Number:
WIPO Patent Application WO/2018/147187
Kind Code:
A1
Abstract:
A low-temperature cryopanel part of this cryopump is provided with two cryopanel members (62) disposed on both sides of a low-temperature cooling stage with a cryopump center axis therebetween. Each of the cryopanel members (62) is provided with: a bow-shaped flat part (75), having a circular arc portion (78) and a string (79); and a first bent part (76) integrally formed with the bow-shaped flat part (75) and connected to the bow-shaped flat part (75) at a portion of the string (79). The bow-shaped flat part (75) is thermally coupled to the low-temperature cooling stage through the first bent part (76). The shape of the remaining portion of the string of the bow-shaped flat part (75) of each of the cryopanel members (62) is determined so as to allow the two cryopanel members (62) to be interchangeable without interfering with a refrigerator.
