John Seeman was appointed Assistant Director of
Accelerator Systems for the Technical Division in September. He will
continue as head of the Accelerator Department, a position he has held
Seeman said he has enjoyed his years at SLAC. "It’s been a
great twenty years—a lot of hard work and a lot of good people. I was
fortunate that way."
Seeman’s first position at SLAC in 1982 was as Head of the
Linac Group where he worked on the Stanford Linear Collider (SLC). "The
SLC commissioning was great fun for me and the other accelerator
physicists and managers but at times a little frustrating. Every day a new
accelerator physics effect came up which needed to be understood. That’s
why we’re here! We were creating a new field of accelerator study in real
time. It kept us on our toes."
"We would often stay working until 2 a.m. and then be back
in for the 8 a.m. meeting to report our findings," he said. "When things
got rough at 1 a.m. in the control room, we often said ‘It doesn’t get any
better than this,’ referring to how exciting the results were and we
didn’t want to be anywhere else."
Seeman next worked for PEP-II, where he was System Manager
for the High Energy Ring, PEP-II Deputy for Accelerator Physics and Head
of the Commissioning team.
"The whole team on PEP-II worked very long and hard to get
all the details right and it paid off," said Seeman. "PEP-II commissioned
very quickly and reached world record performances four months after BABAR
was on-line. PEP-II reached its design parameters in about a year and a
"The team did not stop there. Through the work of many
people, we have in practice more than doubled the design-integrated
luminosity per day during the past year. With recent hardware upgrades
PEP-II should do even better with another factor of two increase over the
next 18 months and perhaps a further factor of two over the next four
years. PEP-II has plenty of room to grow."
The future holds exciting possibilities, Seeman said. "For
way down the road, we are investigating the possibility of a Super-PEP-II
that may produce 10 to 100 times the data per day. Future studies will
tell if this possibility looks feasible. We would very much like to keep
SLAC’s trend going."
"SLAC has been a great place to work," Seeman said, "with
exciting people, a supportive environment, new ideas that abound and a
great staff and users. I cannot wait to get started on my next twenty
