Description
In order to study dynamic effects in accelerator magnets, such as the decay of the
magnetic field during the dwell at injection and the rapid so-called “snapback”
during the first few seconds of the resumption of the energy ramp, a fast continuous
harmonics measurement system was required. A new magnetic field measurement system,
based on the use of digital signal processors (DSP) and Analog to Digital (A/D)
converters, was developed and prototyped at Fermilab. This system uses Pentek 6102
16 bit A/D converters and the Pentek 4288 DSP board with the SHARC ADSP-2106 family
digital signal processor. Using this system, a new result on the decay and the
snapback after short injection porches will be presented.
