| Abstract |
An in-vacuum undulator and an in-vacuum wiggler have been developed for CLS at SSRF recently. The period lengths of the undulator and the wiggler are 20mm and 80mm respectively. Both IDs have the minimum gap of 5.2mm. The field integrals were measured for each magnet block with two poles and were sorted in-situ as they were installed on to the girders. Finally the field integrals of the undulator and the wiggler were shimmed by using the 'Magic Fingers' at the ends with a special algorithm. This paper reports the procedure and the results of the measurement and the optimization for the field integrals.
