Vacuum Consideration Pertaining to Bellows Changes on Debuncher Tanks

PDF Version Also Available for Download.

Description

It has been proposed that the stochastic cooling tanks in the Debuncher be modified so that their position can be changed remotely by installing motor driven stands. The present bellows that connect the tanks to the beam pipe vacuum chamber does not have enough radial movement to allow the movement required of the tanks. In order for this proposal to be enacted, the existing bellows will have to be replaced. The present bellows is a formed bellows 5 1/2-inch I.D. x 2-inch long, it will be replaced by a welded bellows 4-inch I.D. x 4-inch long. Due to the smaller ... continued below

Description

It has been proposed that the stochastic cooling tanks in the Debuncher be modified so that their position can be changed remotely by installing motor driven stands. The present bellows that connect the tanks to the beam pipe vacuum chamber does not have enough radial movement to allow the movement required of the tanks. In order for this proposal to be enacted, the existing bellows will have to be replaced. The present bellows is a formed bellows 5 1/2-inch I.D. x 2-inch long, it will be replaced by a welded bellows 4-inch I.D. x 4-inch long. Due to the smaller size of the replacement bellows, its effect on the performance of the Debuncher Vacuum System must be examined. The areas of concern are: pumpdown time, pressure attained by turbos, and pressure in the high vacuum range.
