Heat Shield W.O#: 42752-7 
Status: In progress 
Subject: P2N Setup - LP-FEBIAD target 

Inserted a used (heating) LP-FEBIAD target with a basic heat shield assembly with no end plate foil on the window side to observe heating. The P2N Coil / TGHT connections were added.

Test whether the TS connections are affecting the P2N heating or if it's the P2N target itself.

-Heat the TGHT only, observe, then ramp down.

-Heat Coil only, observe, then ramp down.

-Heat TGHT w/ Coil, observe, then ramp down.

Note* Heating should be even across the target. Elog & take pictures.

NO HV ALLOWED!!!!
