Second Generation

Section of ANASEN with twisted wire configuration
A simulation, showed the Anode wires, the Cathode wites, the SuperX3 Silicon Detector, and QQQ Silicon Detector. The simulation shows Anode-9 and Cathode-15 are hit.

The main difference from the 1st generation is the Twisted Anode and Cathode wires.

Basics Geometry

SuperX3 Silicon Detector Array

A drawing of SuperX3 silicon detector

There are 24 Super-X3 double-sided Silicon detectors on the wall of the ANASEN. They are placed 88 mm away from the beam axis. Each of them has 75 mm X 40 mm sensitive area. Thus, the super-X3 covers a forward and backward angle of 40 deg.
