This page aims to thoroughly describe the TCT setup used at the physics department of UZH. It starts by introducing the setup, the hardware and connections, and the software to run the tests. The pulsed infrared laser used in TCT (1064nm wavelength) passes through an optic fiber which splits in two section where one is 20m longer than the other. This leads to having two similar pulses with a time difference of 100nm. The beam then is applied on a sensor, with an amplifier and an oscilloscope.
Setup The setup in mounted inside a cold box for low temperature applications. The test sensor is installed on a fixed plate underneath the laser. The laser can be moved in a range of 10cm*10cm*10cm with a resolution of <1 micron.
