    Mailing Lists

    This is a list of mailing lists

    These are restricted for organizational purposes.

    Institutional Board: this is a limited group representing the PI's of all the institutions. hmstk-lb-ib

    Executive Board: this is a restricted group with the executive members on it according to the bi-laws. hmstk-lb-eb

    Technical Board: the technical board will be a restricted email list with only the working group leaders and a few other members. hmstk-lb-tb

    Project Coordination Group: this is a restricted group including officials from the national labs. to provide oversight to the Project. hmstk-lb-project

    These are the main lists for water Cherekov detector

    Collaboration This list is for both water Cherekov and liquid argon efforts. This is now the official collaboration list. hmstk-lb-collab

    An earlier list of interested individuals is still available, but will slowly be eliminated.

    Water is the mailing list for those involved in designing the water Cherenkov detector. hmstk-lb-water

    This list has no function at the moment. hmstk-lb-general

    Working Groups for water Cherekov detector.

    Phototubes: scope of work includes PMT evaluation, procurement, production, mounting structure design, pressure performance, installation. hmstk-lb-pmt

    Electronics: scope of work includes bases design, cables, front end electronics, data acquisition and calibration. hmstk-lb-electronics

    Vessel and water liner: scope of work includes the structure of the vessel that holds the water, alternatives for the vessel includes stainless liner, concrete liner, geo-textile liner, and other alternatives. hmstk-lb-liner

    Water System: Scope of work includes the basic untrapure water system, material compatibility, Future development needed for Galolium loading, cooling system. hmstk-lb-watersystem

    Integration: scope of work includes integration of all subsystems. hmstk-lb-integration

    Software: scope includes physics simulations, reconstruction, online data acquisition, offline data processing, software infrastucture and software management. hmstk-lb-software

    Calibration: scope includes detector calibration systems, associated hardware, software, and analysis. The end result should be a method for calibrating the energy, time, and particle identification for the detector, and associated cost and schedule. hmstk-lb-calib

    US long baseline neutrino experiment study

    The link is HERE

    This study was carried out between March, 2006 and June of 2007. It's primary mission was to understand the capabilities in the current and future program of accelerator neutrino oscillation physics in the US, from FNAL. It also informed the NuSAG (Neutrino Scientific Advisory Group of the DOE/HEPAP) about these capabilities. The NuSAG committee used the findings of this study to issue its report in July 2007.

    The report of the study has detailed information about the event rates from various beam configurations from the main injector at FNAL. It also has the best possible information available at that time on technical issues regarding detector performance, feasibility, and cost.
