I think Walmart might sell equipment that could be classified as a
particle accelerator. (But the particles involved are not subatomic!)

Well, a CRT based TV set of yore already qualifies as a particle
sccelerator. Although the particles are just electrons,
and the energy range is keV, not GeV or above.

Well, I happen to work in a lab similar to Cern,
though somewhat smaller.
IT evolution in sites like that is not that much
different from the rest of the world.
VMS and mainframes were ubiquitous at the end of the 1980s,
but that changed rapidly in the course of the 1990s
in favour of Unix and later Linux.
In such organisations, the various divisions may have different
preferences as far as their IT is concerned, so the science divisions
might run some *X, while the PR guys run M$.
Accelerator controls usually have several IT levels,
where the lowest level runs some realtime OS (e.g. VME-based),
whilst monitoring / visualization may well run on M$
(or even VMS in days gone by).

Rear wheel's rim is a goner. Haven't checked yet, but I think no spokes
broke. The car's bumper hit my rear wheel and seems to have "locked in"
and just pushed the wheel on the wet road. At one point, I started to go
sideways and my backpack landed on the guy's hood and I guess I then
just slid down to the ground. I was *completely* unhurt. (perhaps a bit
of a state of shock). The backpack probably took the brunt of any impact.

Yes they did ! All of them intact ! But the tiramisu cake (frozen) was
squashed, so I have a pretty good idea where on the backpack the impact
occured. The juice carton survived, but showed some signs of "stress"
(for lack of better word).

I'm at SLAC. (First site in North America to have a web site, which
originally ran on now-mothballed big IBM iron.) There are multiple
accelerators and equipment here. In my division, SSRL, we have a synchrotron
ring and a dedicated injector. Those are primarily run by VMS systems. The big
Linac is primarily run by VMS systems.

I'm given to understand that the accelerator physics community has largely
gotten behind a control system called EPICS, which is developed on Unix
systems, and many new installations therefore use Unix/Linux systems. People
here have ported Epics to VMS. Some of our experimental stations run on Unix,
and we have a big facility that, last I looked, was on Irix.


SLAC has an assortment of web servers for internal and external use, and
the ones run by central IT are on Windows (mostly) and some Linux systems.
SSRL's webservers (which I'm in charge of) are VMS-based (Alpha and
Itanium). What runs your webserver has very little to do with what runs
your physics hardware.

I'm not an expert, but the short answer would be that it depends on your
design and your existing hardware. SSRL inherited the early-1970s SPEAR
ring and has been through two massive upgrades, but there's still a lot
of custom hardware and electronics in it, I think. If you started out to
build it from scratch, you could do a lot more with off-the-shelf systems.

(Note that these projects are *huge* and take a long time to put together.
If you started to build SPEAR now - not that big of a machine - you might
come online in 2017 if you were lucky. That would be about five incompatible
Windows architectures from now.)

There are some vendors (*cough* Kinetic Systems *cough*) who sell interface
cards and no longer provide VMS drivers, and who don't upgrade the existing
drivers for new VMS versions.

I don't know about running the accelerator, but when I was introduced
to particle physics I was told that you "collect your data on a
PDP-11 and analyze it on a PDP-10".

That was a couple years before DECshipped the first 11/780. The
particle physics group bought the cheapest system DEC would ship:
1MB RAM, 64MB disk (I think), one 9 track, one LA36, no FPA. We
added 1 DZ-11.

Has the linear accelerator that paralles the San Andreas been shaken

Uh, they phased out VAX/VMS in the 1990's and phased in Linux and both
were to analyze data. At least one accel. lab I know was switching
from VMS to Unix for online data acquisition ca. 1990, but that's the
word when I was there ca. 1987. As for what ran the accelerator
itself, I never knew. Others ran it at the other end of the very long
building. All we cared was that we got beam.

Got beam? :-D

No FPA?! When I was "replaying my data", our FPA died and I actually
felt it in reduced speed. Then I measured it and -- lo and behold it
went from ~ 27 events / CPU-sec down to ~ 18 events / CPU-sec, IIRC. I
asked system management to look into it and they said the FPA died. I
didn't even know we had one, much less that there were such
creatures.

So what did you have? A VAX 11/750?

No. As I said it was an 11/780. 11/750 had not yet been announced.

Parallels? I think it _crosses_ it.

We got whacked very hard in 1989; no particular earthquake trouble since, as
far as I know. (My part of the lab, the synchrotron part, now runs a dedicated
injector - an accelerator of its own, although it's circular, not linear -
so we aren't at the mercy of the big linac. The LCLS project, finishing
construction now, does use the first third of the linac.

Yep, you're right. I missed that part between "Superman!" and "And

Well, you wrote:

"

All you said here was that you used the pdp a couple of years before
the first 11/780. Then you said the cheapest DEC system, but not when.
When you said the cheapest system it sounded to me like it could be
any system, not just the 11/780, even if it was at the time of the
first 11/780. DEC didn't have anything cheaper than a VAX 11/780? Even
a non-VAX (or does the LA36 only work on a VAX)?

Sorry, I guess I read it wrong or just didn't know enough history --
or both! or whatever.

Question about accelerators:

So, you have one big 27km loop.

Do they inject particles and accelerate the even particles clockwise,
and the odd particles counterclockwise, and each side has 13km to
accelerate until they hit at the other end of the loop ?

Or are they able to put particles into collision-free paths around the
loop so that they can each travel/accelerate for long periods, circling
the loops many times and only once they've gotten to the right speed, do
they press some button that changes the course ever so slightly so that
particles in opposite directions will the collide just under all the
monitoring equipment ?

It is the latter:
The two beams in LHC travel in their own vacuum tube each (inside the
magnets).
Injection and accellaration takes some time until stable beams are
stored. Only then collisions start: at the interaction points inside the
detectors the two tubes cross and a few protons collide (this crossing
is steered by a kind of "kicker" magnets). The beams are not single
particles but bunches, so they are not destroyed immediately, but this
goes on for many hours until a new filling is needed.

> Injection and accellaration takes some time until stable beams are
