1. SPEAR3 Beam Line Upgrades
Objective:
Upgrade beam line optics, etc to facilitate optimal exploitation of the SPEAR3 source characteristics.
Schedule:
all front ends 500mA capable on SPEAR3 startup (Fall, 2003)
all ID beam lines 500mA capable in 2004 (resources permitting)
all bend beam lines 500mA capable with filtering and/or aperturing by 2004 (resources permitting)
Funding:
DOE BES, DOE BER, NIH NCRR, PRT, ...

2. SPEAR3 - Beam Line Upgrades Program Elements
evaluate and optimize beam line functionality in the context of the present/future user community needs
mask, filter, window, and optic upgrades as required to cope with the power increase
focusing optic upgrades to
faithfully image the source
position monitor, optic, and support structure improvements to preserve SPEAR3 stability
shielding modifications to ensure SSRL continues to operate safely
new insertion devices for BL4/7 to fully utilize the SPEAR3 source characteristics and provide new capabilities

3. SPEAR3 Beam Line Upgrades
Most beam lines will experience optics improvements but relatively modest conceptual changes.
There are, of course, exceptions to this rule. A few of the more notable exceptions proposed are:
BL5-2/3 where the locust monochromator will be replaced and the beam line optimized for eV operations (currently eV);
BL7-2 where the conventional toroidal mirror focusing system will be replaced with a cylindrical mirror and sagittal focusing monochromator for improved high energy performance;
BL4-3 & BL7-3 which will obtain collimating mirror optics;
BL6-2 where the optics will be transformed to a double mirror system similar to 9-2, 9-3, and 11-2 and optimized for >5000eV operations;
BL3-3 where the beam line will be optimized for eV operations;
BL8-2 will be optimized for eV operations with the inclusion of a grating multilayer and reconfigured mirror optics;
BL4/7 which will benefit from new 20 pole, 2.1T wigglers.

4. SP3 BL Upgrade Schedule resource constrained schedule:
all front ends 500mA capable on SPEAR3 startup (Fall, 2003)
all ID beam lines 500mA capable in 2004 (resources permitting)
all bend beam lines 500mA capable though perhaps not operating ideally by 2004 (resources permitting)
