Facilities at Laurentian University

Facilities at Laurentian University

• Jacques Farine
• SNOLAB Workshop III
  Sudbury 12 may 2004

Rationale

• To support the underground experiments, proper
  laboratory and working space on the surface is
  necessary
• preparation of the resins and adsorbers that are
  used in the trace radioactive assays
• chemical separation of the radioactive atoms
• radioactivity counting facilities
• mix of laboratory space, clean assembly space, a
  workshop, computer rooms, and general office space

Creighton mine is 20 km from Sudbury and
Laurentian University

• independent research facilities are necessary at
  the site, with space required for counter
  development, assembly and testing
• surface laboratory will require a
  low-radioactivity chemistry laboratory with fume
  hoods for solvents and acids, sinks with regular
  and ultra-pure water, and provision for chemical
  waste collection
• Policy that no radiotracer studies involving
  liquid radioisotope sources are to be carried out
  at the SNO surface / U/G labs to prevent
  contamination

Creighton mine is 20 km from Sudbury and
Laurentian University (II)

• ongoing radiotracer testing program at LU
• support of SNO's radioassay program
• carried out by SNO staff and visiting scientists
• this program will persist/grow with more
  low-background experiments on site
• migration of radioisotopes in fluids
• most current proposals/prototypes based on fluids
• purification of cryofluids may require more
  investigation
• counter development / staging area
• SNO, SK same counters used for Ra/Rn assay
  program as for program development
• can probably no longer be the case for next
  generation techniques
• hence this area needs to be isolated from site

Current Facilities Off-site

• One-Ton Test Facility (Carleton, Ottawa) - far
• Chemistry Lab (Laurentian, Sudbury) - small

Status

• 2/3 of desired space identified (1000 sq ft)
• detail design in progress w/ Physical Plant
• transformation during summer 2004
• facility available for equipment in fall 2004
• actively looking for more space for counter
  development
• start to define needs from various experiments
