Notes:
LH= 2 Position means: LH2 + Vacuum window + entrance window + exit window + He cell heli= um gas
LD= 2 Position means: LH2 + Vacuum window + entrance window + exit window + He cell heli= um gas
C = positions means C only
Ho= le position means Hole only
Ou= t position usually means out only, but could include Flyswatter
Ra= diator means Raidator + Flyswatter, usually. Sometimes just radiator.
Fl= yswatter can be in or out in conjunction with ANY of the other targets, in principle.<= /td>
Normally it would be used in conjunctio= n with the radiator target or by itself.
An= independent set of "hole targets" or "halo targets" is located on= the short G0 girder.
