Kaon Aerogel Detector prototype - PMTs comparison
In order to compare the different PMT options we may have to install in the Kaon Aerogel Detector, a set of cosmic rays data was acquired with the CUA's prototype. Details of the prototype can be found in the Prototype page.
All the other configuration of the prototype were kept the same, just the PMT was exchanged between one test and the other. The setup was configured as follows:
- Cosmic ray configuration (two triggering PMTs with scintillator on the top and bottom of the prototype)
- 08 aerogel tiles with 1.030 refractive index
- Mylar covering the internal walls of the prototype
- High voltage of -1.80 kV on the PMT

PMTs at CUA
The group is performing different experiments with some PMT to construct a tool to analyse the equipment that will be used in the aerogel detector.
Since the Summer 2011, the Nuclear Physics group at CUA is performing tests on the following PMTs:
- PMT model XP4500B S/N 09641 (with electronic base #101)
- PMT model XP4500B S/N 09650 (with electronic base #102)
- PMT model XP4500B S/N 01414 (with electronic base #100)
- PMT model XP4500B S/N 09561 (with electronic base #102)
Previous analysis of PMT's gain
The University of South Carolina had analyzed the PMT before it comes to JLab. It was done in the summer of 2011. The plots with the main characteristics of each PMT, separated by its serial number, is shown in Gain Plots.
A table with these data can also be download as a spreadsheet: File:PMTcatalog.xls.
Position dependence of incident photon
Details on the step motor that are being used in the position dependence experiment can be found in the following links:
