چکیده

We estimate the short-range wake elds in the W-band active matrix linac of a 5-TeV collider, and demonstrate that for the assumed 60-pC bunch c harge and 10-m rms bunch length they are acceptable. Abstract. We estimate the short-range wake elds in the W-band active matrix linac of a 5-TeV collider, and demonstrate that for the assumed 60-pC bunch c harge and 10-m rms bunch length they are acceptable.

Calculating the Loss Factor of the Lcls Beam Line Elements for Ultra Short Bunches*

The Linac Coherent Light Source (LCLS) is a SASE 1.5-15 Å x-ray Free-Electron Laser (FEL) facility [1]. Since an ultra-short intense bunch is used in the LCLS operation one might suggest that wake fields, generated in the vacuum chamber, may have an effect on the x-ray production because these fields can change the beam particle energies thereby increasing the energy spread in a bunch. At LCLS ...

Transverse Quadrupole Wake Field Effects in High Intensity Linacs*

Transverse quadrupole wake fields exist whenever the beam is not round, and therefore in an alternating gradient focusing system these fields cannot be eliminated. As a result, these fields represent a potential limitation on high intensity linac performance. In this note we calculate the magnitude of quadrupole wake field effects for the SLAC linac. (Submitted to Particle Accelerators) *Work s...

Dosimetric Evaluation of Linac Photon Small Fields using MAGIC Polymer Gels

Introduction: In radiotherapy, methods of treatment planning are becoming increasingly more complicated. This requires verification of the doses delivered to increasingly smaller and more precise regions. Radiotherapy techniques are continuously employing smaller and smaller field sizes to deliver tighter radiation doses with higher therapeutic ratios, generating interest among researchers to p...

Experimental Demonstration of Wakefield Effects in a 250 GHz Planar Diamond Accelerating Structure

We have directly measured the mm-wave wake fields induced by subpicosecond, intense relativistic electron bunches in a diamond loaded accelerating structure via the dielectric wake-field acceleration mechanism. Fields produced by a leading drive beam were used to accelerate a trailing witness electron bunch which followed the driving bunch at an adjustable distance. The energy change of the wit...

X-band Crab Cavities for the Clic Beam Delivery System

The CLIC machine incorporates a 20 mrad crossing angle at the IP to aid the extraction of spent beams. In order to recover the luminosity lost through the crossing angle a crab cavity is proposed to rotate the bunches prior to collision. The crab cavity is chosen to have the same frequency as the main linac (11.9942 GHz) as a compromise between size, phase stability requirements and beam loadin...
