5.1.3.6 DC Power

Q1, the small SACLAY quadrupole, has a Danphysik supply rated at 5V @ 3500A. Q2 and Q3, the large SIEMENS quadrupoles, have a FUG supply rated at 10V @ 2000A. Additionally there are eight (8) trim coil supplies for each SIEMENS magnet (total 32) fed from Lakeshore Supplies rated at 100A @ 30V. Finally the large WANG NMR dipoles, on each arm, have a Dynapower supply rated at 10V @ 2000A. Before powering any magnet it is important to ensure that nothing is inadvertently touching the leads and that the dump resistor is always connected. Make a visual inspection to ensure that these conditions exist and that there is no one working on the magnet. A light switch on the Gantry Platform activates a Red Strobe light which warns personnel that magnets are operating on a particular spectrometer.
