Can’t touch too much at the high level

Important though is XPOC

Collimators

Serious prototyping and testing done

Development still going on at the middle level.

Big system, lot of work to get the full system singing and dancing.

LHC Timing

All LHC processes (e.g. injection, ramp,...) will be synchronized and triggered using timing events Sent by the LHC Timing System

LSA provides services to manage these events Creation, modification Loading to and unloading from the

High level applications


FIDEL

Using data from series cold measurements FiDel models components of total field in aperture of magnet

Set of parameterized equations - fit to the measured behaviour of the set of magnets in a circuit


MAD & FIDEL


FiDeL status Data collection has advanced at a reduced pace. Data available today

covers about 60 % of the magnet families and work is in progress to complete the LHC Magnetic Archive.

The work has focused on: preparation of the structures for the synthesis of the model

parameters (machine layout), storage of the parameters (database supported by AB-OP), retrieval and use of the parameters (FiDeL in the LHC controls).

Tracking tests were performed in the benches of SM-18 to verify the accuracy of the model: 2 dipoles (MB2598, MB2624), 1 SSS (SSS064), powered through LSA, implementing the FiDeL algorithm for field

forecast and correction, verified B1 tracking among sectors, B2/B1 tracking among main

quadrupoles and dipoles, b3 and b5 correction at each dipole. Fruitful AT-AB collaboration in the preparation, running and

evaluation of the test results

Luca Bottura


The integral dipole field in two MB’s track on average within 1 unit of B1, with peak error of 2.5 units of B1 and reproducibility from cycle to

cycle well within 1 unit of B1 (including measurement errors !)

The ratio B2/B1 tracks on average within 0.01 unit of tune Q, and the reproducibility from cycle to cycle is within the tolerance window of 0.003 unit of tune (including measurement errors !)

1 unit of B1

0.003 units of tune Q

Analysis by P. Xydi, AT-MTM

FiDeL tracking test results 1/2


The reproducibility of the b3 compensation, on two MB’s, same powering sequence, is 0.1 units of b3, equivalent to 5 units of chromaticity (excellent !)

The compensation of the integral b3 in a single dipole, using the FiDeL algorithm, has an error of 0.25

units (quite good !)

Integral b3 before compensation

Integral b3 after compensation

Analysis by N. Sammut, AB-OP

10 units of chromaticity

FiDeL tracking test results 2/2

Luminosity optimization etc Spec in progress

K-modulation SLAC

Collimator scans Work in progress

Measurement procedures: aperture, dynamic aperture, matching, scans

Triggered acquisition – data collection and organization

Interface to feedback systems

On-line Aperture Model

And a lot, a lot of details: settings, FIDEL, configuration…

DEPLOYMENT AND TESTING


Testing Currently use unit testing (automated black-box testing) for

business logic and Data Access Objects

GUI applications are tested manually Logic operating on the database development DB Hardware access usually on a real hardware (or test

FGCs)

Goal setup a testing hardware environment which could be used for a systematic testing (before each release) Lab FGCs, Beam Instrumentation


Deployment and testing


Dry injection run –next weekOptics As usual, ramp and squeeze…

Settings Power converters, RF, Kickers, Collimators, Bumps, injection point steering

FIDEL 450 GeV – decay, transfer functions for 78

Timing BST, GMT, timing tables, events, telegrams, injection request, application, sequencer

Kickers Timing, control, analog acquisition

Power converters ~ 250 in voltage simulation mode

Collimators FSM, settings, monitoring, drive

Screens Control, acquisition

BPMs, BLMs, WS, SRMs Event triggered acquisition

Standard facilities Mode, FD, logging, alarms, RBAC


Collaboration

Good collaboration between Operations, Controls and Hardware groups.

Remarkably fruitful collaboration with Fermilab LAFS (Project Leader: Dave McGinnis)

RBAC (Suzanne Gysin) Wire Scanners (Elliot McCrory) Synchrotron Light Monitors (Dennis Nicklaus) Valuable input on sequencer, tune etc. (Jim Patrick, Jerry Annala,

Dean Still) “Possible” future projects: luminosity monitors, rest-gas monitors,

Schottky monitors, triggered data acquisition


Conclusions

Majority of LSA functionality has been implemented. It has been deployed and tested. Now in exploitation phase - harness functionality to meet

LHC requirements

Staged approached for deployment and testing: Individual systems, HWC shadowing, dry runs, magnet

measurements

Devil, as always, in the details - still a lot to do…
