Using television cameras to measure emittance

PDF Version Also Available for Download.

Description

Since the luminosity in a linear collider depends on the horizontal and vertical emittance (epsilon/sub x/, epsilon/sub y/) as 1/..sqrt..(epsilon/sub x/epsilon/sub y/) a possible method for improving the performance would be to decrease one or both of these numbers. Once this has been done in a damping ring for example, great care must be taken to avoid effective emittance growth in the remainder of the collider. Therefore an effort should be made to measure epsilon, (x and y), as accurately as possible, both during machine development and operationally. One technique used for measuring epsilon is to insert a luminescent screen ... continued below

Description

Since the luminosity in a linear collider depends on the horizontal and vertical emittance (epsilon/sub x/, epsilon/sub y/) as 1/..sqrt..(epsilon/sub x/epsilon/sub y/) a possible method for improving the performance would be to decrease one or both of these numbers. Once this has been done in a damping ring for example, great care must be taken to avoid effective emittance growth in the remainder of the collider. Therefore an effort should be made to measure epsilon, (x and y), as accurately as possible, both during machine development and operationally. One technique used for measuring epsilon is to insert a luminescent screen in the path of the beam and measure the size of the spot of light made as the beam passes with a television camera and some associated electronics. This has advantages over sampling type techniques (such as wire scanners) because it provides full pulse to pulse two-dimensional information.
