LHC injection dry run

LHC Injection Dry run - December 2007

Objective: first cross-system test of beam based systems to exercise:

Timing and synchronisation
High level equipment control: pulse kickers, power converters, TDI, screens
Acquisiton: Beam Instrumentation (BLMs, BPMs, Screens, BCT, SRMs) & beam dump

using high level control room software.

Would aim to set-up using stand alone applications (LSA for the most part) and then drive sub-set of machine through 450 GeV operational phases: pre-injection plateau, ramp to injection, injection plateau pre-beam, injection using machine sequencer. Include as much of TI8 as possible.

When: Friday 14th & Monday 17th December 2007

Friday: individual system tests outline
Monday: As a collective from sequencer.

INDIVIDUAL HARDWARE SYSTEMS

		LSA	Requirements	Aux	S/W	Hardware
Timing	Define events. Construct timing tables. Forewarning events must be generated from a table that you load that is triggered from HIX.FW-CT, this is just a normal timing table loaded by OP as usual. A system task triggers production of HIX.FW-CT when the SPS extraction forewarning arrives.	V0.1	Need application up and running and debugged. Configure, load and send tables. Change & Monitor contents of telegrams (TGM video tool - crank it up for the LHC). Check subscription. Distinction between fast extraction event for CNSG and LHC in the SPS? LHC as master - set.		Delphine	Julian, Stephane, Ioan
Power Converters	As many as Steve Page can give us (expect around 200) Act HW Group 'DRY RUN DEC 07'	V0.1	injection, ramp&squeeze - test what ever we can get hold of - in voltage simulation. Cold magnets a possibility if available. Would be looking for several hundred converters in total.	logging, monitoring	Mike	Stephen Page
RF	Monitor?		Not this time. No pre-pulses. (Although could imagine monitoring ongoing commissioning.)		Delphine	Andy
Injection Kickers	Kicker parameter space (include kick strength), Kicker control application Acquire waveform - OASIS	to do	plus make rule, discrete trim (check - should go trim)	logging	Lasse/GHH	Etienne
TDI	Test settings and monitoring. By the way, it will be difficult to move the real TDI's for the injection test because they have not yet been properly HW commissioned however I propose to use our prototype at the collimator workshop for the injection tests: it is fully operational and we can treat it as a TDI as far as the software is concerned!		Stefano's application, settings, trim	logging	Stefano	Kadi
Beam Dump	Monitor, XPOC		XPOC - more space, more space....		Jerome	Bren
BPMs	Concentration - capture & FIFO	V0.1	BPM logging and fixed displays for TI8 setting BPM bunches and turns setting BPM sensitivity (low/high) - from equip state, sequencer fixed display - first turn FIFO, first turn capture (Jakob) naming convention? layout versus MAD	sdds logging??	Marek M.	Lars
BLMs	Concentration	V0.1	TI8 BLM - running display (fabio?)	logging	Marek M.	Lars
Screens	Control, acqusition	to do	Display, logging, VIDEO		Fabio, Guy	Lars
BCT	Acquistion	V1	Display, logging		Markus	Lars
Fast BCT	We can basically acquire selected bunches over consecutive turns.		prepare a first version of an application concentrating on the DabCapture mode and probably also provide a fixed display for the standard Acquisition mode (all bunch intensities averaged over 227 (?) turns)		Markus	Lars
Lumi Monitors	Acquire & display				Markus
Wire scanners and sync light monitors	Start applications and displays				Elliot
BIC	?Not sure what's going to be there.		Not there - not installed

CORE

		LSA	Requirements	S/W	Hardware
Optics	Twiss/Strengths/Generation	V0.2	Define supercycle for test. Injection, ramp & squeeze Issues: actual optics name, reading settings (12 seconds), generate warm correctors, trim - DBP name, trim - makerule problem	Marek S
Knobs/MAD	Injection bumps, injection point steering, septa		TI8/LHC cross over MSI, kicker knobs from YASP	Verena, Jorg
Database	Parameter space etc. etc. etc.	V0.1	ramp & squeeze, power converters, kickers, instrumentation,	Chris, Delphine, Mike
FIDEL	Harmonics, decay, snapback	V0.1	Injection plateau	Marek S.
Mode	Definition, distribution		Publish...	Mike, Reyes, Greg
Timing	Monitor contents of telegrams			Delphine	Julian, Stephane, Ioan
DIP	Experiment communication		Define signals to push and pull. - how do we push?	Markus
RBAC	Aim for a full vertical slice			Suzanne	Steve Page

APPLICATIONS

		LSA	Requirements	Aux	S/W	Hardware
YASP	Acquisition and correction The acquisition of the BeamThreading stuff is working in YASP (for the first turn) for a selected crate. In principle I could go for more crates, but I will wait now for the concentrator. The sensitivity switching is also operational. Check settings (read & trim) & optics.		YASP - Jorg For BPMI, I have defined everything that exists in MADX. For the threading data I will in parallel prepare a direct access to the FEs, because I need that for testing and I'm sure this will work even if the concentrator is late... For the BPM sensitivity, this will also be available in YASP. I just have to find the WF device names.		Marek M., Jorg
Sequencer	Multi system Drive	V2.0	Sequence definition		Reyes, Mike
Fixed Displays			BLMs - No Trajectory - No Slow BCT - Markus Screens - Markus Page 1 - mode - Markus Dump status - not this time Kicker status - Jakub/Markus TI8 BPMs - No
