Abstract
An application accelerator system for monitoring the gain of a free electron laser. Coherent Synchrotron Radiation (CSR) detection techniques are used with a bunch length monitor for ultra short, picosec to several tens of femtosec, electron bunches. The monitor employs an application accelerator, a coherent radiation production device, an optical or beam chopping device, an infrared radiation collection device, a narrow-banding filter, an infrared detection device, and a control.
Claims8
An application accelerator system comprising:
- an application accelerator;
- a coherent synchrotron radiation production device;
- an optical beam chopper;
- a coherent synchrotron radiation collection device;
- a narrow banding filter;
- a coherent synchrotron detection device;
- and
- a control.
A method for monitoring the gain of a free electron laser including:
- producing an incoherent beam of electrons at relativistic speeds with an application accelerator;
- converting said incoherent beam of electrons into a coherent beam of electrons with a coherent synchrotron radiation production device;
- optically chopping said coherent beam of electrons into separate packets of particles with an optical beam chopping device;
- focusing said packets of coherent synchrotron radiation into a tighter beam with an infrared radiation collection device;
- filtering a specific frequency of radiation from said coherent synchrotron radiation;
- and
- detecting said filtered frequency of coherent synchrotron radiation with an infrared coherent synchrotron radiation detection device.
