Initial Demonstration Of 9-MHz Framing Camera Rates On The FAST Drive Laser Pulse Trains

TL;DR

This paper demonstrates the use of a Hamamatsu streak camera as a framing device to capture 2-D images of laser micropulses at 3- and 9-MHz rates, relevant to accelerator physics, with initial proof of concept using an OTR source.

Contribution

It introduces a novel configuration of a streak camera as a framing camera for high-rate laser micropulse imaging, enabling new temporal and spatial diagnostics.

Findings

Successful recording of 2-D images at 3- and 9-MHz rates

First demonstration of a streak camera in a semi-framing mode with an OTR source

Potential application to accelerator and synchrotron radiation studies

Abstract

We report the configuration of a Hamamatsu C5680 streak camera as a framing camera to record transverse spatial information of green-component laser micropulses at 3- and 9-MHz rates for the first time. The latter is near the time scale of the ~7.5-MHz revolution frequency of the Integrable Optics Test Accelerator (IOTA) ring and its expected synchroton radiation source temporal structure. The 2-D images are recorded with a Gig-E readout CCD camera. We also report a first proof of principle with an OTR source using the linac streak camera in a semi-framing mode.
