The field of the magnetic channels has been included also. The simulation of them magnetic shield for the stray magnetic field has been presented briefly. A method has been described to ascertain the position and magnitude of the coil misalignment.

Bending magnets, switching magnets, analyzing magnets, quadrupoles, sextupoles, Glasers, etc. are examples of accelerator magnets. In most of the accelerator applications, especially in high resolution beam lines and also in synchrotrons and storage rings the field quality of the magnets have to be very high. The field quality in room temperature iron magnets depends mainly on the shape of the pole. Various methods of determining the pole profile have been discussed.

This facility has been successfully commissioned in 1999. In the synchrotron, a current of 11 mA has been achieved at 450 MeV. Two out of three bunches from the  synchrotron have been successfully extracted and injected into Indus-1 storage ring. Maximum current of 161 mA was accumulated in the Indus-1 storage ring. Beam dynamics studies carried out on these machines during the commissioning are described in this paper.

In one of the operations, the control on some of these devices was lost. The reason for this was the total damage of fibre optic cable. An indigenous fibre optic connector was developed and a patch was connected in place of damaged cable by using these indigenously developed connectors. Apart from this a new system, for absolute position read hack of foil stripper, is designed, fabricated and installed in the accelerator at NSC. Foil stripper at terminal is used to convert negative ion to positive ion and its stripping efficiency depends upon its health. There are 200 stripper foils in NSC 15 UD pelletron accelerator and it is important to know the condition or each stripper for the operation of accelerator. This position read back system helps to know the status of stripper. in use, accurately. Use of two turbo pumps modifies gas stripper system used in SC 15 UD accelerator. During test run it was observed that the operation of turbo pump controller, used for the operation, was not up to the mark. It broke down twice during the test run. The controller was then modified for its proper operation. Page(s): 87-95 Mon, 01 Jan 2001 00:00:00 GMT http://nopr.niscpr.res.in/handle/123456789/25135 2001-01-01T00:00:00Z
