The Large Millimeter TelescopeThe Large Millimeter Telescope

• The largest single dish mm The largest single dish mm telescope - the largest science telescope - the largest science project in Mexicoproject 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

The Large Millimeter TelescopeThe Large Millimeter Telescope

• Unique multiwavelength companionUnique multiwavelength companion– flux level: 3 mJy Hz-1/2 (1)– day and night– 1º/s slewing on both axis

• Complemented with Sierra Negra Complemented with Sierra Negra Consortium experimentsConsortium 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

• Site permit granted by SEMARNATSite 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)


The HAWC site: weatherThe 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



The HAWC site: Moderate WeatherThe HAWC site: Moderate Weather

Fast wind (>25 mph) less than 5% of time

Occasional influence of hurricanes

Dean! max wind speed: 90 MPH

Water for HAWCWater for HAWC

• Water demands:Water demands:– HAWC tanks/3 years = 0.8 l/s– 2M gallons/ 100 tanks

• Water acquisition systems Water acquisition systems (by preference):(by preference):– well @ 1-2 km from site– water trap @ 7 km from site– transport from lower wells with

trucks (15km)



Water for HAWC: the wellWater for HAWC: the well

• Location of potential wells Location of potential wells through topographic and through topographic and geoelectric studiesgeoelectric studies– advised by collaborators

from Geociencias UNAM and UAM

– permit granted by SEMARNAT
