Hey Matt

Nice catch!  My fingers are good for slipping typos...  :o)

Shoulda been +4K, actually reading site up to +10K
  Another interesting point, the resonators at these
extreme Q's show a propensity to go into mechanical
and electrical resonances that can dynamically effect tuning
based on temperature differentials, vibration from
infrastructure, etc.

Another point, even through beam ways look like they
could be occupied, area is completely off limits while
accelerator is "BEAM ON", X-rays in area would nuke
(literally) you in seconds.  My physics colleague (Ph.D.
candidate) worked at JLabs on the FEL program, and
has been through the EHS training (rad, RF, HV, laser,
cryogenics, etc. etc.).  They take safety "VERY"
seriously there.  They have had the beam line "compress"
(i.e. lose vacuum violently) when an arc-over in a resonator
punctured the Neobyium resonator and cryogenic He
reserviour, took nearly a month to replace damaged
components and reestablish hi-vacuum in beam path for
full-up operation.
