Overview
The CAEN Mod.N914 is a 8 channel charge preamplifier and integrator, implemented in a single-width NIM module. It is designed to process signals generated by Photomultipliers. The module is provided with LEMO 00 connectors for both input and output signals, except the T# output which is provided through a 16 pin flat cable connector. The Photomultiplier signal at the input is buffered and processed in several ways:
- The OL# output provides the signal processed by a gateless charge preamplifier and integrator.
- The OH# output provides the signal processed by a gateless charge preamplifier and integrator, followed by a 10x gain stage.
- The OLSUM output provides the analog sum of the OL# outputs.
- The OHSUM output provides the analog sum of the OH# outputs.
- The ASUM output provides the analog sum of the CH# inputs.
- The MALU output provides a step function (Majority) with a height proportional to the number of channels simultaneously over a threshold settable individually or globally.
- The T_OUT# output provides a discriminator output converted into a LVDS signal to be sent to a TDC for arrival times recording.
