Background and interests of group members:
Steve:
background soucres, linacs, power sources
wishes: LUX, source test stand,
more investments into laser expertise ... will be everywhere
synchronization, isochronous transport
LCLS support - Steve Milton?
experiments at ALS, APS
Walter:
CERN
PhD thesis on IR, IP, ...
plan for future - slicing - ...
potential ideas for dynamic change of contraints during matching
...
Hiroshi:
Used to be supervisor of Johan Bengtsson
2 pet projects: molecular storage ring; collaboration with Chris Timossi
background: master thesis - field theory - part of neutrino group at Tokio -
sold to KEK because working to much on computing
worked on oldest light source in Japan (17 m, 350 MeV)
PhD thesis on Landau cavities - Tristan
1985 to LBNL
Warren:
in the 1960s started at nuclear test reactor of GE, near Pleasanton (580/680),
50 MW, to produce neutrons, radioisotopes, ...
Based on USGS concerns ... shut down for a while ... went out of business
There still is a small 50 kW reactor for neutrography there
Always was interested in accelerators ... Heard as a kid of Bevatron. Came
to Bevatron - enjoyed optimizing - hands on machine. When it shut down joined
ALS in 1992. Joined our group in 2000? Interests: Optimizing the injection system...
Preparation for top-off. Loves trouble-shooting.
Weishi:
Until early graduate level in China. Early 90s came to US. Michigan State graduate.
Also received his PhD from Michigan State. Postdoc at University of Colorado.
Charged particle optics. Later Fermilab, Oak Ridge, LBNL.
Always lattice ... Now also microscopes (potential growth areas), insertion devices, beam dynamics.
Interest is single particle dynamics ... Likes to also be able to do some
experimental work now, verifying calculations on machines.
Greg:
Names is associated with Matlab ... and ID controls. Math undergrad. Master in signal processing
and controls. Algorithm guy (not circuits). Missile guidance systems in Maryland? Then came to
LBNL in 92/93. Supposed to do feedback ... But Alan decided machine is stable enough without feedback.
Did ID controls, automation, Matlab routines, middle layer ...
Now being used at SPEAR, CLS, NSLS VUV+X-ray, ...
Wants to keep this as background project. But feedback use will increase with tighter tolerances.
Interested in it. Plus signal processing of experiments.
Tom:
Material science at Cal. Dave Atwood got him interested in ALS (Steve as well). When money run out
after university needed job. Bob Miller gave him chance as operator 8 years or so ago. Learned
everything operational from Warren. Joined our group 3 years ago. Controls, matlab high level,
many accelerator physics tasks, noise/vibration, ... volunteer for Web and group promotion efforts.
Material science: Operations used to be stepping stone to beamline jobs. However, after a while
in operations started to like accelerator physics more.
Agusta:
Grad student ... Background: Here to acquire it. Coherent SR simulations and experiments. Where she wants
us to go: More often to lunch (with her actually being invited). Problem with location, geographical spread
of group. Hopes to graduate in a year ... John as supervisor, but often away ... Fernando and me? Looking
for postdoc closer to Iceland.
Fernando:
Studied in Italy ... Just after University was very lucky to get contract in the accelerator division.
Did pepper pot as thesis ... Then started DAPHNE for about 10 years. Had chance to follow all phases
of the design. Linac, accumulator, double ring collider ... Reponsible for injector. Strong involvement
in beam diagnostics, commissioning, ... After commissioning was not clear what would happen at Frascati,
started to look - applied here - became Greg replacement. Took the chance to move here. Very positive
experience ... Brother is at CalTech.
Continued with beam diagnostics. Circe ... Enjoys diverse user group ... diverse projects: cold electron
source - some words later.
Christoph:
Got into accelerator physics as undergraduate, doing control system programming
at ELSA (Bonn University). Learned real time operating systems, distributed
control systems. Later some nuclear physics (intermediate energy particle physics).
Diploma thesis on ion trapping and two stream instabilities, PhD thesis on spin
dynamics in a ramped electron storage ring (ELSA). Effect of stochastic nature
of synchrotron radiation on crossing of depolarizing resonances. Collaborated
with DESY (Derbenev, Brinkmann) on high energy electron cooling. Came to ALS
in 1999 (after PhD), started with transverse single particle dynamics, frequency
maps. Very lucky to get that opportunity. Diverse interests (operations, control
system, feedbacks, single particle dynamics, collective effects). Would like
to participate in any new project, but believe we can find very interesting
things to do with ALS as well.
David:
originally field theory - then accelerator physics
likes accelerator physics because it is a very nice combination ...
Thesis was in quasi isochronous rings - renaissance with CSR stuff. Was doing single particle stuff
at the ALS until I came. David got into management, not that he wanted to. Meeting with Alan in PRD
round ... Told David that one should be agressive in plans 'I want your job'. Next year - asked - Alan's
response was why? Vladimir - Alan eventually left ... Australian light source.
Can guide things now ... Weishi, Hiroshi, and me doing work. Worked OK with Johan, but does not want to
be his boss. Personal interest in charged particle optics. Quasi isochronous. CIRCE. Ultrafast ...
But also what can we do with the ALS!!! Coherence might be more
important ... ?
