Neutron Source
~ 73.7% availability in 2005/2006~ 1350 neutron beam days
AECL succeeded to extend the operating license beyond 2005 and is preparing a request to operate to an approximate horizon ~2012.
NRC Senior Executive are engaged in coordinating a discussion in government to formulate a recommendation for a longer term replacement – the Canadian Neutron Centre.

5 thermal-neutron spectrometers operating 24h/day, 7 days/week.
Beam Lines
N5 Upgrade in progress
2 beam lines under development

N5 Upgrades
Goals: Reduce radiological hazard from beam stop and beam channel Improve beam hazard indication Reduce background for measurements (factor of 10 improvement)– Increase signal for measurements (triple-axis)– Control system upgrade – first “production” roll-out / D3 prototype– Make N5 an attractive alternative triple-axis to C5, reducing clash
with reflectometry applications in the short term
Activities in 2005-2006:– Replaced the articulated detector / 2A shield with an integral
shielding package, similar to the low-background design on C5;– Installed a tall diffracted-beam channel, purchased PG for analyzer
and monochromator (quality unacceptable – returned to vendor);– Made progress on motor control system to C5 standard;– Discussed concept of shielding around the incident-beam channel to
reduce gamma-ray fields near the specimen table.

Delays
• Financially driven: – Change in AECL-NRC agreement led to underestimated costs (50%),
prematurely exhausting budget– Reduced budget/revenue year
• Human Resource driven: – AECL priorities compete for design and fabrication resources– CNBC priorities: User-experiments, D3 Reflectometer, other
• Commissioning discoveries:– Heavy door, requiring re-design and fabrication
![Page 11: Canadian Neutron Beam Centre Status Report to CINS Annual General Meeting John Root , Director](https://reader031.vdocument.in/reader031/viewer/2022013012/56815b81550346895dc97ef1/html5/thumbnails/11.jpg)
Further Work
• Phase 1: Functioning instrument suitable for many experiments and establishing final requirements– Adjustable beam stop– Rapid operation beam shutter– Remaining commissioning– Detector calibration– Software & hardware integration – Electronics repair and upgrade
• Phase 2: Final T3 instrument – Multiple incident beam configurations– Outer water shield if required– Vacuum features added if required

CNBC Proposals
Proposal Review Procedure … something to note
1. Upon receipt of a Proposal, the Director will ensure that a Local Contact has been assigned, and will forward the proposal to the Review Administrator.
2. The Review Administrator will register receipt of the Proposal, assign a number (e.g. CNBC-123), and deliver it to the Local Contact.
3. The Local Contact will review the Proposal, in consultation with the Technology Group Leader and the primary Proponent to:
a) ensure that the proposal is correct and completeb) evaluate the effort and cost required to mitigate any identified hazardsc) ensure that the experiment is feasible with CNBC equipment
4. Within one week from receipt, the Local Contact will either send a message of rejection (with reason) to the Review Administrator and primary Proponent, or return the correct and complete Proposal to the Review Administrator, for scientific review (cc primary Proponent).
5. The Local Contact may recommend which … etc…. Scientific Review NEXT

CNBC Proposals
Proponents are responsible to indicate on their proposals any hazards associated with their requests.
Discussion at an early stage enables us to figure out if and how to mitigate risks.
Categories include:– Explosive– Radioactive– Biologically active– Corrosive / reactive / flammable / toxic …
