Topic: photo-multiplier’s dynamic range improovements
contextualization
- 1 ms - 1 – 10 mA
Problematic
Linear mode Saturation mode
avalanche effect
Why saturation?
Test Box
First results SIMULATIONS• Actual system :
- loading time ≈ 30 ms- Needed Capa on the
last stage ≈ 10 mF (Huge and not possible)
EXPERMIMENTS• Actual system
- Saturations- ≠dynamic ranges btw
PM
First qualitative experiment with the box
V config 1 linear tension devideurV config 2 curved tension devider
Next Weeks
• Define more precisely when does the saturation mode begins • Run mesurements with several
types of electronics • Write the users notice of the
testing box in english
Main Objectiv
Design and suggest a new electronic socket to improove the dynamic range on photo-
multiplayers and avoid saturation and unlinear signals in beam profiling
