Application Specific

Free-electron lasers (FELs) based on superconducting accelerator technology and storage ring facilities operate with bunch repetition rates in the MHz range, and the need arises for bunch-by-bunch electron and photon diagnostics. For photon-pulse-resolved measurements of spectral distributions, fast one-dimensional profile monitors are required. The linear array detector KALYPSO (KArlsruhe Linear arraY detector for MHz-rePetition rate SpectrOscopy) has been developed for electron bunch or photon pulse synchronous read-out with frame rates of up to 2.7 MHz. At the FLASH facility at DESY, a current version of KALYPSO with 256 pixels has been installed at a grating spectrometer as online diagnostics to monitor the pulse-resolved spectra of the high-repetition-rate FEL pulses. Application-specific front-end electronics based on MicroTCA standard have been developed for data acquisition and processing. Continuous data read-out with low latency in the microsecond range enables the integration into fast feedback applications. In this paper, pulse-resolved FEL spectra recorded at 1.0 MHz repetition rate for various operation conditions at FLASH are presented, and the first application of an adaptive feedback for accelerator control based on photon beam diagnostics is demonstrated.

An infrared spectrometer is described which uses a 32-element InSb linear array detector. The infrared linear array (IRLA) spectrometer collects infrared spectra with a spectral width of 0.50 µm every 16 µs. The performance of the IRLA spectrometer is characterized with respect to signal-to-noise ratio, spectral resolution, time resolution, and instrumental line shape. The IRLA spectrometer is used to collect the time-resolved infrared spectra following 193-nm irradiation of a solution of Mo(CO)6 in hexane.
