PM05 | Optical Transmission Line For Streak Camera Measurements at Pitz | 98 |
|
||
The photoinjector injector test facility at DESY Zeuthen (PITZ) [1]
produces electrons with a momentum of about 4 MeV/c. It is the aim to
measure the temporal characteristics of the electron bunch train and
single bunches with high accuracy of the order of 1 ps and less. Several
types of streak cameras will be used in combination with different
radiators which transform particle energy in light. The problem to be
solved is the light transport over a distance of about 27 m. Basic demands
to the optical system and design principles will be explained. The
optical and technical solutions will be presented. The strategy of
adjustment and commissioning of the optical system will be described. The
system contains switchable optics to use different radiators (OTR,
Cherenkov radiators). Diagnostic tools are foreseen at different
positions along the optical axis. The results of different measurements
in the lab and using the original system will be presented. The problems
on the minimalization of the time dipersion in the system will be
discussed.

PT22 | Measurement of the longitudinal phase space at the Photo Injector Test Facility at DESY Zeuthen | 222 |
|
||
The photo injector test facility at DESY Zeuthen (PITZ) has been developed with the aim to deliver low emittance electron beams and study its characteristics for future applications at free electron lasers and linear accelerators. The energy of the electron beam varies in the range between 4 and 5 MeV. One of the important properties of the delivered beam is the longitudinal phase space of the electron beam. Measurements of the momentum distributions show a small energy spread. The principle of the measurement of the bunch length will be discussed, time resolutions will be shown and preliminary results will be given. The design to measure the correlation between momentum and time distribution of the electron bunch will be shown with calculated resolutions. | ||
PT23 | Transverse Emittance Measurements at the Photo Injector Test Facility at DESY Zeuthen (PITZ) | 225 |
|
||
The main research goal of the Photo Injector Test Facility at DESY Zeuthen (PITZ) is the development of electron sources with minimized transverse emittance like they are required for the successful operation of Free Electron Lasers and future linear colliders. The process of electron beam optimization requires characterization of the transverse emittance at a wide range of operation parameters. The design and functionality of the emittance measurement system at PITZ is presented. The methods applied as well as the resolution limits of the system are discussed. The latest measurements of the transverse properties of the electron beam are presented. |
