LHC portal

We need some web based one... No software install

If someone knows how to do it right quick... Lets do it now

Both beams dumped <sighs> I gotta be somewhere tomorrow morning and it's 1am here.

You'll just all have to make history without me . . .

beams dumped

Page 1 back up....

Danny: Poor Markus... Page 1 has been freezing and stuff..

For IRC, some java applet/webstart exist, but you still need to open, and most likely register, a chat room on a irc server.


Also, today IRC clients are integrated in a lot of IM softwares.

Can you help me find something.. I will set it up now if I can...

Links ? Ideas ?

Beams "debunched" thats interesting.... CMS

So we still have beam... But the Page 1 and LHC-OP cant see it CMS Page

Ok Here it comes

4X4 collisions..... CMS

CMS status page says collisions coming next:

6 Dec, 2:15, 4x4 Collisions to come next

LHC informs us that we go for 4-on-4 bunches with collisions next.

stable beams are..

The history of why we care about debunched beams... Firstly the bunch-train profile of the LHC has a big gap (the abort gap) at the end which allows the dump kickers to ramp up with no particles passing, otherwise it would spray them as the kicker ramped.

The Tevatron has an identical dump setup - you don't want to ramp kickers with beam. On one occasion, a fully accelerated beam was in the Tevatron when for a variety of reasons the beam debunched. This means that you lose the abort gap. A beam dump was triggered, but with no abort gap, and with CDF (one of the Tevatron experiments) just upstream of the dump kickers, their silicon detector got sprayed with very high energy protons, wiping out a proportion of the sensing and electronics.

The LHC has protection mechanisms in place to ensure that debunched beam dumps are safe(r), and these need to be tested, along with all the other machine protection systems.

The most popular IRC server are here:

Still need to find a good web client.

Lost Page 1....

Yes I found a IRC place... We could just use a room of our choice with no on in it... Rude as that is....

Lemme play with it for a minute

Ok we could try out this one..

Go to http://searchirc.com/irc-LHC-1 and choose #2 by clicking the #LHC...

Hey it says LHC doesn't it ?

Lets see if everybody can use it...

Im already in the room as user 127
