Laboratory Office Buildings Five in fully built-out configuration
Main loading dock and road access to center of ring
Service Building- one per pentant
Spaces for nine long Insertion Device Beamlines.
One is allocated for the project nanoprobe beamline (in red).
Lengths >250m possible.
…. gives about 6m of extra beamline length on experiment floor.
Extra 10’ of floor length
Normal vibration isolation joint position
Alternative vibration isolation joint position
Refer to Drawing LT-XF-CF-1008 for full dimensions of all beamlines.
Very standard floor access aisles
Need access to ID FEs only (30 doors)
Tunnel floor is 200mm higher than experimental floor (beam height at 1200mm, and 1400mm on experimental floor).
Sector floor layout designed to optimized space.
Safety emergency egress requirements
Strong preference to include a duck-under route wherever possible to meet the 75’ “common path of travel” in BCNYS regulations.
Some alternatives if a duck under is not compatible with the scientific requirements
High beta straight area with extended floor. Note that building over the egress aisle is justified only by scientific requirements and requires express written approval. The aisle will be relocated taking a portion of the BM/TPW sector.
First Optics Enclosure (FOE)
End Station 1
Duck under route(relocated)
End Station 2
Egress aisle(relocated with permission)
Storage Ring Tunnel
BM-B Dipole Magnet
BM-A Dipole Magnet
IR beamline passes over useable BM beamline
IR beamline passes under BM FE, through ratchet wall to unusable ID floor area*.
* There are three unusable ID ports, (2 x RF and 1 x injection)
* Shielding given is for sidewalls/roof/downstream wall, in mm.
See also document “Guidelines for NSLS-II Beamlines and Front End Radiation Shielding Design” by Job and Casey, May 2008 for explanation and assumption.
Relatively Minor Variants for Canted Configuration and Damping Wiggler Beamlines.
6” Conflat on isolating gate valve,
centerline 1400 mm from experimental floor,
155mm downstream of nominal shield wall position.
A note on vacuum isolation;
Differential pumps, with fast sensors can be used with approval from the vacuum safety committee. Beamline isolation windows are not mandatory.
* copies will be available on request within ~two months, the information within is NOT required for the proposal.
Total = 38,000 gsf
Each Lab = 480 nsf
Initial list produced for space estimation purposes only.
LOB build package includes benches, sinks, cupboards , safety shower, etc.
Removable / specialist lab equipment will be part of separate budget.
The five machine shops around NSLS-II will be expected to specialize to some extent – for example one of the five may have a larger milling machine.
The LOB plans are available for viewing (heavy set of drawings)!
