The ALS is a 1.9 GeV storage ring operating at 500 mA of beam current. It is optimized to produce intense beams of soft x-rays, which offer spectroscopic contrast, nanometer-scale resolution, and broad temporal sensitivity. The ALS facility includes an accelerator complex and photon delivery system that is capable of providing the foundations for an upgrade that will achieve world-leading soft x-ray coherent flux. The existing ALS provides a ready-made foundation, including conventional facilities and also includes extensive beamlines (up to 40 simultaneously operating beamlines) and instrumentation, an experimental hall, computing resources, ancillary laboratories, offices, and related infrastructure that will be heavily utilized in an upgrade scenario. The ALS will be upgraded with a multibend achromat (MBA) lattice design that will provide a soft x-ray source that is orders of magnitudes brighter — an up to 100-1000 times increase in brightness and will provide a significantly higher fraction of coherent light in the soft x-ray region than is currently available at ALS. Any resulting Subcontract will be between the University and the party identified as the Subcontractor and will be issued under Prime Contract No. DE-AC02-05CH11231 between the University and the United States Government (hereinafter “U.S. Government”), represented by the Department of Energy (hereinafter “DOE”) for the management and operation of LBNL and the performance of research and related work. 4.2 Description of Items Beam Position Monitor (BPM) electronics assemblies provide signal conditioning, timing distribution, and processing necessary to measure the transverse position of the particle beam. The assemblies consist of multiple printed circuit board (PCB) sub-assemblies grouped into major functional assemblies, including the Timing + Balun assembly, Analog Front End (AFE) assemblies, and Chassis-level electronics. The required assemblies for this work package are summarized in the table below, which identifies the BPM major assembly, sub-assembly description, total required quantity, and the associated drawing number that defines fabrication and build requirements.
