GEM Results (January)

 

 

Pad Response Function

 

Distribution of amplitudes for each channel at each point
Distribution of amplitudes scaled by signal on last GEM foil for each channel at each point

Spread and error of scaled amplitudes vs scaled amplitude

Pad Response Data for January 23, 2004 Data
for MM fit, please go to the top of the MM page

Normalized Pad Response for Gem TestCell. The responses have been scaled so that the peak is at 1 and have been overlaid.
Fitted Response using all the pads and this fit routine

In the above fit, it appears that the first 16 points are shifted. These points were taken on a different day than the rest of the data set. The first 16 points were shifted so that they were alligned with the rest of the data and the pad responses for pad 22,23,24 were fitted.

Pad 22 Response


Pad 23 Response


Pad 24 Response

The distance between the pads appear to be consistent with
having a pad width of ~2mm. The distances are as follows:

Pad 22 --> Pad 23 = 2.03 mm
Pad 23 --> Pad 24 = 1.88 mm
