Title: Vacuum exhauster
Inventor: ISOBE SHIYOUJI
IPC: F04B37/02
Filed: 1979-04-25
Abstract: PURPOSE: To minimize the heat of radiation transmitted to liquid helium and reduce the consumption of the liquid helium by making the chevron surface facing a cryopanel side such a surface that no radiation heat absorber is coated in order to practically maximize its reflection factor.  
     CONSTITUTION: Of four chevron surfaces provided vertically and before and behind of the channel parts 28 of the chevron baffle 20, only the surface 30A facing the cryopanel 12 side is polished for finishing so as to obtain a mirror state having a maximum reflection factor, and the other three chevron surfaces 30 are coated with a black paint as a radiation heat absorber. Thus, the external radiation heat QF is reflected at the chevron surface 30 at each stage and absorbed by the black paint as a radiation heat absorber each time it is reflected, whereby no heating of the liquid helium occurs due to its arrival to the cryopanel 12. Thus, the consumption of expensive liquid helium can be reduced.
