IntroductionIntroduction

SM18


Mandate of the magnet test facility:

- 1232 dipoles + 460 quadrupoles have to be cold tested at CERN

- 12 benches built, organized in 6 clusters of 2 benches (SM18 building)

- Wide range of local (per cluster) or shared (mobile rack) equipments

- Magnet presence on the bench VS number of tests to execute



Constraints for the tests & measurements:

- Several applications have been developed to assist the tests and measurements

- Fast and easy setup of the applications

- Taking into account specific calibration of the used devices

- Limit as much as possible the manual edition of the configuration files

- Traceability of the used equipments is requested by the QA rules

Definition of a Test:

From the TEMA point of view, a test is :

- A list of commands

- From a set of pre-defined commands, dedicated to an application

- Used to execute a measurement with a list of specified equipments

- On a local test bench









Definition of a Sequence:

From the TEMA point of view, a sequence is :

- A list of tests

- Used to execute a set of measurements & to drive the equipments

- On a local test bench







The TEST MASTER fulfills the first 2 constraints:

- Management of several applications to assist the tests and measurements- Fast and easy setup of the applications

What about :

- Calibration parameters of the devices- Manual edition of the configuration files- Traceability

- Bar code scanner

- Industrial portable computer

- Wireless communication

- Connected to the equipment DB



Calibration databases

The calibration data are taken from :

- CFB & magnet temperature probe coefficients DB

- Coil coefficients DB

- Power supply DCCT DB

- …



Auto configuration

A set of scripts have been developed to :

- Compare the needed & present equipments for a dedicated test.

- Access to the calibration DB and generate setting files for the dedicated applications.

- Build and transfer on the local test bench workstation the final configuration file.



But what about the Magnetic Measurements …

… at SM18 the MM are managed by the MMP6 application

Automation of the magnetic measurementsAutomation of the magnetic measurements


MMP6 is made of 4 modes of use:

The HARDWARE mode:

Selection of the equipmentsHardware configurationTest of the communicationsTest of the equipments



The RUN mode:

Selection of the magnet typeSelection of the measurement param.Selection of the current cycle



The MEASUREMENT mode:

Execution of the current cycleControl of the equipmentsExecution of the MMReading of the integratorsSaving the data



The DISPLAY mode:

Analysis of the dataInfo. about over range / out of limitsArchiving of the raw data & results



From the TEST MASTER …

… to the MM analysis



From the TEMA:

Selection of the bench (1/2)

Selection of the test to execute (ie : MM)

Click on Run Test button

Then all the following actions will be done automatically …



On the HRS:

Extraction of the present equipments from the DB

Comparison with the needed one for this MM

Extraction of the calibration parameters

Configuration file generation for MMP6

Transfer of the config. file on the cluster workstation



On the cluster workstation:

Launching of the MMP6 application

Execution of the commands for this test



On MMP6:

Execution of the HW test of the equipments

Execution of the magnetic measurement

Display & online analysis



From the users:

Checking of the MM status & limits

Acceptation of the test

Archiving of the raw data

ConclusionsConclusions


- The integration of the Test Master, Hardware Recognition System and MMP6satisfies the constraints specified for the test benches facility.

- The full system is in use since few month. The performance is very satisfactory,with a good reliability.

- A lot of time has been saved during the phases of measurement and softwareconfiguration.

- The experience of HRS will be taken as an example in the view of an adaptationfor the LHC.
