	Funding: DOE As the length of insertion devices (ID’s) increase for synchrotron light sources, so does the need to have larger ultra high vacuum (UHV) sealed chambers, which in turn necessitates the use of creative ways of sealing these large chambers in the UHV range (10^-11 torrs).The method specified below was used to seal a 4 meter test vacuum chamber successfully in the ultra high vacuum range. This method could be used for sealing ID chambers of lengths larger than 4 meters too due to its simplicity and reduced cost advantage.

THPAC14	3D Hall Probe Calibration System at Insertion Device Magnetic Measurement Facility at BNL	1169

	Hall probes are commonly used to measure local magnetic field, however they need to be calibrated. This paper describes the accurate 3D Hall probe calibration system developed by the NSLS-II Insertion devices group. The calibration system and the calibration curves are presented. An Arepoc 3D Hall probe used to characterize the Insertion Devices (IDs) has been calibrated. The probe contains three sensors oriented perpendicular to each other in order to measure three components of the magnetic field. The three Hall sensors are mounted on a circuit board and their active area dimensions are 0.05 mm x 0.05 mm with a linearity error up to 1 T less of 0.2%.

	The National Synchrotron Light Source II at Brookhaven National Laboratory (BNL) is a storage ring of 3 GeV electron beam energy that will provide ultra high brightness and flux and exceptional beam stability using advanced insertion devices (IDs). The magnetic characterization of these devices is important to achieve these performances. In order to perform precise and accurate measurements of the NSLS-II IDs, several recent improvements on actual magnetic measurement system have been developed. The system includes a flipping coil bench to measure the first and second magnetic field integrals and a Hall probe bench to perform magnetic field measurements of different types of IDs. The main features of the hardware system, control program and the recent improvements in the magnetic measurements system are presented.
