Title: Cryo pump
Inventor: MATSUDA SHINZABUROU
IPC: F04B37/08
Filed: 1981-01-14
Abstract: PURPOSE:To enable sharp reduction of thermal load to a cryo panel accompanying sticking of sputtering particle by reversing opening direction of chevron above and below a beam shaft and reducing an area where sputtering particles stick. CONSTITUTION:A chevron 4 has its opening direction reversed above and below a beam shaft 3. For this reason, a surface 7 where sputtering particles stick becomes small in its area. A central face 12 of the chevron 4 opposed to the beam shaft 3 has a large area where sputtering particles stick but since this part does not exert any influence upon radiation reaching a cryo panel 5, it offers no problem even though radiation rate is lowered. Furthermore, no sputtering particles stick to a surface corresponding to the face 12 where radiation at room temperature can reach the cryo panel 5 by reflection of only one chevron. Accordingly, thermal load to the cryo panel 5 can be reduced by a large margin.
