Big pulse due to scope 1 M ohm scope resistance

Pulses in the following to detectors are huge due to we used wrong scope resistance of 1 M ohm.

IAC NAI_1

Without Mu material:

HV = 700 V

IAC NaI Det1 Scope 1.png

With Mu material:

HV = 700 V

IAC NaI Det1 Scope 2.png


IAC_NAI_2

With Mu material

HV = 700 V

IAC NaI Det2 Scope 1.png

Tests with 50 Ohm Scope Resistance

All the following tests are done under 700 V.
