Sweep Magnet #2

The magnet which we will use for the second sweep is a DW magnet on permanent load from the FEL group.

Sweep Magnet #2 Power supply

I asked Bill Merz to recommend a power supply for this magnet. He suggested a few companies Original mail from Bill . Based on this I decided to base the preliminary design on the Genesys power supply which is the newer version of the lambda power supply.


The Genesys 15-220 is a 2U high 15V 220A 3.3kW remotely programmable power supply. The model number is Gen 15-220- -1P230 for the 230V single phase version.

The back of the power supply is shown below. The power supply can be controlled by either RS-232 or using analog control lines on the J1 connector. A proposed system design is also presented below based on RS-232 readout. The RS-232 connector is connector 5 in the figure and the analog programming connector is number 3.

Sweep2 System Design

A first proposal for the interlock for the magnet is shown below. This system will require someone to push a button to enable the poser supply and in the event the power supply fails for some reason it will not automatically switch back on.

The design is summarized in the following Excel document. Excel summary.
