Introduction I hope everyone knows the terms from the title of the post. I thought quite a lot whether it was worth writing them or not. But nevertheless I will explain the meaning of terms. Cryogenic temperatures should be called temperatures below 120 K. Cryogenic devices are those whose actions are based on the use of superconductivity phenomena at very low changes. Further SRF – Superconduction Radio Frequency. Theory In the superconducting photoinjector of bERLinPro the photocathode (electron source) is held at 80 K. During operation the photocathode suffers from heat load due to RF- and laser power. A study was made of heat transportRead More →
