Beta Test the New SLAC Travel System

SLAC Today

Monday - June 12, 2006

In the ILC, both electrons and positrons will be created on one side of the accelerator; the electrons will be directly injected into a damping ring, while the positrons will have to travel the length of the accelerator before being injected into their own damping ring.

Designing a Particle Superhighway

In the International Linear Collider (ILC), electrons and positrons will travel in the fast lane, eventually smashing into each other with unprecedented energies. Yet before the particles can begin their journey down the linear accelerator, they need to make it to their respective starting lines, 30 kilometers apart. This task is more difficult than one might expect.

Due to technical constraints, both the electrons and positrons will be created on one end of the machine. The electrons will be fed into the nearby damping ring and then into the linac, but the newly created positrons must travel all the way down to the other end of the accelerator before turning around and accelerating back toward the collision point. Precisely guiding this beam over such a long distance is a challenge.  Read more...

Félicitations au LAL

Accelerator-based science is possibly the most collaborative of all the major fields of "big" science. Competition to be the "discoverer" rather than the "validator" is both healthy and a key ingredient for producing outstanding science. Notwithstanding this often very intense competition, laboratories, detector collaborations and individuals openly share detailed information on new concepts, novel ideas their development and optimization across the full spectrum of research tools.

So it is for several SLAC programs. While BaBar and Belle compete to discover new physics before the other, PEP-II and KEKB help each other on a continuous basis, sharing what each learns about machine performance or helping each other to maximize future improvements or fix known problems.  In addition, our highly experienced SSRL staff is often involved in helping with the design, implementation or improvements of other synchrotron light sources worldwide, all of which compete for very similar scientific "prizes."  Read more...

Beta Test the New
SLAC Travel System

(Graphic - Travel Form) The SLAC Domestic Travel System, with the assistance of a great team of administrators and travelers, has been completely redesigned. One of the benefits of the new system is the ability to track the travel authorization process step-by-step. Travelers will also be able to pre-populate the travel authorization with information from prior trips.

However, the travel office needs your help to test the new system. As with most new systems, there are still bugs to work out. Additionally, we want to know what we can do to improve and simplify the process while still maintaining compliance with Department of Energy (DOE) regulations.

The public beta test will run for one week from today (Monday, June 12th). If there are no showstopper bugs, the new travel system will go into mainstream use on Monday, June 19th.

You can find additional information on the beta test here.
