GSI Helmholtz Centre for Heavy Ion Research
Ultra-sensitive Beam Intensity Measurement
At the GSI beam instrumentation group new diagnostics devices are permanently developed to match the requirements of the upcoming Facility for Antiproton and Ion Research (FAIR) at GSI/Darmstadt, Germany. One of the major fields of research is the non-destructive measurement of beam intensity in the high energy beam transport sections and in the storage rings. In the frame of a preceding Mari-Curie fellowship, extensive investigations on a superconducting SQUID based Cryogenic Current Comparator
(CCC) for intensity measurements down to the nA range have been performed.
This device measures the beam intensity via the beam magnetic field (fT-range), which requires meticulous shielding. The results from the prototype measurements led to the design of an advanced CCC for FAIR, which shall be installed in our Cryring@ESR facility.
The work related to this topic covers a large spectrum of topics in the accelerator field, like mechanical design, vacuum, cryogenics, superconductivity, electronics, simulations, control applications, beam operation, data acquisition etc. The goal is the setup, commissioning and successful operation of the new FAIR CCC in Cryring, as well as its optimization and comparison with other diagnostic schemes.
The fellow will work in the field of high-end technologies, on an interesting and challenging device, which combines numerous aspects of physics and technology.
