Abstract

Superconducting undulators provide higher magmatic field to increase the brilliance and photon energy of synchrotron light sources. To quantify the amount of beam-based heat load of storage rings and optimize the design of cryogenic system, Lawrence Berkeley National Laboratory (LBNL) proposed a cryogenic calorimeter to perform the working condition of superconducting undulators. The calorimeter has been developed by Shanghai Institute of Applied Physics (SINAP) and installed on storage ring of Shanghai Synchrotron Radiation Facility (SSRF). Also, online experiments started in September of 2012. This paper describes the cryogenic system and beam-based heat load measurement system. Also, some measurement results are given in the paper.
