Development of magnet and associated power supply system for g - factor measurement setup

The measurement of g factor is a crucial tool to understand the nuclear structure. The transient magnetic field is one of the technique to measure the g factor of nuclear states with lifetimes of the order of several pico second. There are various elements involved for success of such a measurement. The most important requirement is to generate transient magnetic field (of the order of MGauss) inside the ferromagnetic target. To achieve this transient magnetic field it is necessary to polarize the ferromagnetic target using a external magnetic field. To extract the information about the slope parameter (which is directly connected to the g factor) a switching magnetic field is required. The duration of the magnetic field is also required to optimize the error associated with the slope parameter. These parameters should be programmable depending on the experiment. A magnet and its power supply system has been designed, fabricated and developed in house at Beam Transport Lab., IUAC to meet the above requirements
