2 Introduction

TJNAF requires an aluminum vacuum chamber (i.e., Upstream Enclosure or USE) for use in one of the experimental halls at the laboratory, see Figure 1.

The USE is welded vacuum chamber entirely composed of AL 6061 aluminum alloy. Its main function is to maintain a nominal - 1 x 10 -3

Torr vacuum while supporting internal and external components. It houses Toroidal Magnet 0 (TM0) and various collimator elements. The enclosure has two primary mating components – the Top Hat and Baseplate, sealed with an O-ring.

The Top Hat is a welded assembly resembling a rectangular box with external ribs. The primary sealing surface shall be machined after the components are welded together to nullify the warping effect due to welding, ensuring necessary compression of the O-ring between Top Hat and Baseplate. Two flange assemblies are installed on the Top Hat, one on each end. The Baseplate is an aluminum weldment structure featuring a 2” thick main plate and 1” thick external ribs. It features several cut-outs for feedthroughs, an O-ring groove, and various hole patterns.

The vendor may recommend improvements to the design, for economy or ease of fabrication, if the specifications mentioned in this document can be met. Such changes shall be reviewed and approved by

TJNAF prior to fabrication.
