Life from the samplers
Lamp saturates pixels in small ~8x8 pxl region
Life from the samplers
Mask eliminates all hits except a 10x10 region where the laser is known to be
Two laser positions + non-laser refernce
Observation when masking pixels
A few pixels in region2 showed hits despite being masked… was always the same ones
Should probably make a list of bad pixels with a full mask and apply in post-processing?
A fine scan of shaper pixels
(samplers were masked during these runs)
Laser fired at points in a line with 10 micron separation
