  1. The HAWC Site & the Mexican Collaboration Alberto Carramiñana INAOE, Mexico Jordan Goodman HAWC Review - December 2007

  2. The HAWC site The base of volcán Sierra Negra • latitude : 18º59’ • longitude: 97º18’ • altitude : 4100m Inside Parque Nacional Pico de Orizaba Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  3. The Large Millimeter Telescope Sep 2006 • The largest single dish mm telescope - the largest science project in Mexico • INAOE/UMass project • 50m aperture @ 80-350 GHz • cold and high redshift universe • in construction since 2000 • 3mm first light in mid 2008 Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  4. The Large Millimeter Telescope • Unique multiwavelength companion • flux level: 3 mJy Hz-1/2 (1) • day and night • 1º/s slewing on both axis • Complemented with Sierra Negra Consortium experiments • HAWC • Solar Neutron Telescope (operational) • 5m radio telescope: Solar + night • cosmic ray array + Fluorescence • two (resurrected) HEGRA IACTs (already in Mexico) • antineutron proposal • Citlaltepetl muon experiment • geophysical and atmospheric monitors Taurus GMC: CO(10) SEQUIOA @ FCRAO 14m 96 sq.deg with 70 m/s resolution www.astro.umass.edu/~heyer/taurus.html Common EG/WMAP Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  5. The HAWC site: easy access Mexico DF 120 km Veracruz 160 km 100 km Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  6. The HAWC site: excellent geographical location Close to the equator: sur= 4 cos(lat) sin()  4(2/3) - 10% more sky access than at 30º - 40% overlap with HESS GP survey - 90% overlap with IceCube - 100% with Whipple Strip Survey and VERITAS Cygnus Survey Crab @ 3º from zenith Galactic center is at 48o Synchronous with Pan-American observatories Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  7. The HAWC site: excellent geographical location Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  8. 90,000 m2 20m contours 30,000 m2 LMT The HAWC site: location and topography 5610m 4582m Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  9. HAWC in Parque Nacional Pico de Orizaba • Site permit granted by SEMARNAT • June 2007: INAOE submitted to SEMARNAT an Environmental Impact Declaration (EID) for HAWC at Sierra Negra • Sept 2007: permit granted for constructing pond and facilities (30,000 m2), water extraction system / with conditions and without permit for road and power line • Nov 2007: detailed road design + basic underground power line design and cost estimate - will submit EID in Dec 2007/Jan 2008 • Jan/Feb 2008: will submit modification of site permit for tanks and revised site layout including two IACTs • March 2008: initiate road construction ( May 2008) Road cost contract : 280k pesos ($26k USD) Power line estimate: 800k pesos ($73k USD) Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  10. The HAWC site: weather Six years of weather data at top of SN available HAWC is mostly weather proof, but look for freezing conditions and severe weather • freezing < 10% of the time Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  11. Day The HAWC site: Moderate Weather Fast wind (>25 mph) less than 5% of time Occasional influence of hurricanes Dean! max wind speed: 90 MPH Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  12. Water for HAWC • Water demands: • HAWC tanks/3 years = 0.8 l/s • 2M gallons/ 100 tanks • Water acquisition systems (by preference): • well @ 1-2 km from site • water trap @ 7 km from site • transport from lower wells with trucks (15km) Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  13. Water for HAWC: the well • Location of potential wells through topographic and geoelectric studies • advised by collaborators from Geociencias UNAM and UAM • permit granted by SEMARNAT Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  14. Water for HAWC: more options • Water trap • pump + gravity • 7 km pipes • permit granted by SEMARNAT Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  15. Site operations • Consorcio Sierra Negra provider of common services (to be adapted from La Palma): • electrical power supply • access road and maintenance • water and sewage • waste collection • security, first aid, fire protection • communications: internet + telephone • base camp • common visitor set up • Cost shared by all CSN partners according to experiment cost, locations, consumptions, etc...

  16. The Mexican collaboration Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  17. The Mexican collaboration Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  18. The Mexican Funding • CONACyT 2006 call for “Ideas de Megaproyectos” • proposals for up to 1000 Mpesos/5 years • 200+ submitted  80 to phase 2 • phase 2: no review(!?)  “research networks” • HAWC in High Energy Physics network Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  19. The Mexican Funding: the HEP network Alberto Carramiñana Jordan Goodman HAWC Review - December 2007

  20. The Mexican Funding: beyond CONACyT networks • Institutional funds (to comply with minimal support): • require 367k pesos/inst/yr to reach 1.5 MUSD/5yrs • INAOE committed 500k/pesos per year (2007: 100 kpesos MEGA + 280 kpesos road + 100 kpesos site studies + travel + ...) • CONACyT basic science projects (“Auger-like”): • call issue on 1/12/7 (deadline 31/1/8) • individuals: up to 1.8 Mpesos /3 years • groups: up to 5 Mpesos /3 years • What about NSF - CONACyT common support?
