  1. E-201 Requests for Run 1A G. Andonian, O. Williams, S. Antipov on behalf of E-201 collaboration FACET Users’ Mtg – August 30, 2011

  2. E-201 Measurements for Run 1A • CCR spectra • 11 tubes, 3 slabs • Breakdown

  3. E-201 needs for Run 1A - 2012 • Fix IP2A (needs set screw) for HeNe injection • OAP Clearance from “off-experiment” beam • Engineering for horn/OAP • Stages/actuator • Mark beam on IP2A and IP2B – establish beam vector (with beam waist at sample) • Requires 2 cameras (with appropriate optics/lenses) • IP2A/2B made of glass (mylar pellicle not fluorescing) • HeNe (with external focusing optics <100um spot) for alignment through tubes • Remote turn-on • TPX window for CCR • “Breakdown Flash” camera • Optics (camera lens) • In vacuum mirror (off-beam line axis) • DAQ Software for interferometer and data logging • Requires moving stage (and readback) • Correlated to pyro signal (ADC readback) • Correlated to charge signal • EPICS panel and tutorials • interferometer • Sample holder stages (x,y,z) • Cameras • Accelerator Knobs for: • flat beams (different aspect ratios up to 100:1 or greater) • varying bunch lengths (15um adjustable to 200um) • Measurement of bunch length • Controlled access • Alignment, install, etc.
