  In this paper commissioning experience of injection into INDUS-2, a 2.5 GeV synchrotron radiation source is discussed. In initial stage of commissioning, partial beam loss was observed. In this context effect of various injection errors such as mismatch between pulse widths, jitter and magnetic field stability of kickers on injected and stored beam are studied1. A brief summary of the results is presented. After reducing jitter and fine adjustments of timings of kicker power supplies, partial beam loss reduced significantly.

  The INDUS-1 is a 450 MeV synchrotron radiation source for the production of VUV radiation. In order to produce the radiation of shorter wavelengths(lc = 31 Ao), a superconducting wavelength shifter (WLS) with peak fieldof 3T is being considered for Indus-1. In this paper, L. Smith's Hamiltonian for Halbach's magnetic field model has been re-derived to estimate focussing component under the compensated electron beam trajectory transformation. Various linear compensation schemes are presented to minimize the linear effects of the WLS and its effects on machine operation are also theoretically studied.
