Resumen:

The Insertion device development and Application (IddA) laboratory of Devi Ahilya University, Indore, India has ongoing activities on undulator design and development[1-3]. In this paper, we analyze the field integral properties of the two DAVV undulator. The first is the IddA U20 prototype NdFeB-cobalt steel hybrid in house designed device of 20 mm period length with twenty five periods. The uniform gap variable hybrid undulator provides magnetic flux density (in rms) from 2400 G to 500 G in the 10 mm-20 mm gap range. The second is the NdFeB based U50II undulator of 50 mm period length with 20 number of periods. Hall probe results are described. A short description of the measurement plan of the undulator on the pulsed wire bench and stretched wire bench is described.
