", "abstract": "Our KISS program has laid the theoretical foundations for probing the epoch of reionization with C+\ntomography measurements, developed unique lithographed millimeter-wave spectrometer technology,\nand initiated a first-light C+ experiment named TIME-Pilot. With KISS support we have carried out the\nfollowing investigations:\n1) Developed the case for line intensity mapping methods to study the epoch of reionization\nusing singly ionized carbon (C+), typically the most luminous emission line in galaxies. The\ntheoretical studies not only explored the amplitude of the signal, and the usefulness in\ndetermining physical properties of the partially ionized intergalactic medium, but also the\neffects of foreground confusion from low-redshift galaxies. Our team made the first\ncalculations of C+ clustering fluctuations from the reionization epoch, and estimated the\neffect of foreground galaxy confusion, largely from CO line emission at z ~ 1. We also\nauthored the first papers on tomographic measurements with the Ly\uf061 emission line, which\nshows great promise for near-infrared intensity mapping measurements with the SPHEREx\nSMEX mission concept.\n2) Developed a complete design for a first-detection instrument of [CII] large-scale clustering\nemission named TIME-Pilot, based on an array of 32 novel waveguide spectrometers. The\nspectrometers are mounted in a linear array in two polarizations, and observations are\ncarried out by scanning the detectors in a 1-deg linear strip, which maximizes depth (small\nsurvey area) while preserving sensitivity on large scales (long scan length).\n3) Demonstrated the key waveguide spectrometer technology, which confines radiation in 2\ndimensions and the power propagates between parallel plates and is dispersed and\ncollimated by a curved grating. The waveguide spectrometers greatly reduce the mass and\nvolume that would otherwise be required with a conventional 3-d grating spectrometer.\n4) Demonstrated a prototype superconducting detector array. These high-sensitivity\nsuperconducting bolometers are mounted on the focal surface across multiple\nspectrometers, and read out by superconducting current amplifiers. The devices present\nunique micro-machining challenges to produce edge-butted sub-arrays that do not leave\nspectral gaps between channels.\n5) Completed the full cryogenic system for the instrument. We commandeered an existing 4\nK cryostat from another project, and added cooling stages to an ultimate temperature of\n220 mK to meet the TIME-Pilot cooling requirements. The system is fully tested and\noperational.\n6) Formed a partnership with ASIAA in Taiwan, led by Tzu-Ching Chang who attended the\noriginal KISS study. ASIAA is providing major hardware components for the TIME-Pilot\ninstrument, and in the past year have developed a prototype of the spectrometer, and\nprocured cables and cryogenic coolers. ASIAA has also become the managing institution\nfor the James Clerk Maxwell Telescope (JCMT) in Hawaii, and ideal facility for carrying out\nobservations with the instrument.", "date": "2019-02-15", "date_type": "published", "id_number": "CaltechAUTHORS:20190213-132441192", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20190213-132441192", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Keck-Institute-for-Space-Studies" } ] }, "doi": "10.26206/BWNS-7F04", "primary_object": { "basename": "Report.pdf", "url": "https://authors.library.caltech.edu/records/bnfw6-v6e90/files/Report.pdf" }, "resource_type": "monograph", "pub_year": "2019", "author_list": "Bock, J.
