S4 Equipment S4 Equipment Three Magnet Families for Testing Three Magnet Families for Testing

Taking into account magnet lengths, cold feet positions , jack positions, powering and availability of magnetic measurement systems, Special SSS units were grouped in 3 main families.

Families:

Family 1: 11670 mm, 10715 mm

Family 2: 9310 mm, 8335 mm

Family 3: 6935 mm, 5660 mm

Equipment Dedicated to S4 TestingEquipment Dedicated to S4 Testing

The anticryostats

For the magnetic measurements on the test benches magnets must be equipped with the anticryostats

Anticryostats of three new lengths are required

The extension modules

For adapting one type of the anti-cryostat to several magnet lengths of one family, extension modules are required. They will be located between the magnet and the MRB

Three types of rigid extension are required

Wide aperture magnets (ø=70mm)

For Q4 in IR1,2,5,6,8; Q5 in IR2,4,6,8; Q6 in IR4, the adaptation pieces have to be developed in order to fix actual anti-cryostats in wider apertures.


S4 and Arc SSS Anticryostat S4 and Arc SSS Anticryostat ProductionProduction

All components ready, except heating elements for S4 families

Missing heaters are due to be delivered these days (today!?)

Production of additional Arc SSS type anticryostats put on stand-by (waiting for the conclusions of this review)


““Mobile” ChaconsaMobile” Chaconsa

All components procured and ready

First system assembled on TBB1 and pre-commissioned (Q9 – family 2)

Support structures of second system are under final assembly stage on the TBD2

Second Chaconsa put on stand-by.

Powering AspectsPowering Aspects

All essential equipment is operational All 13kA commuting switches were upgraded (motorized)

3 major incidents concerning 13 kA cables encountered over 2004 Repair has cost substantial effort and resources Preventive pressure test to be carried out

Two 60/120A commuting switches delivered this week for clusters TBB and TBD

Two 120A Power Converters are still missing


Worries and MishapsWorries and Mishaps

Although over 2004 all essential equipment was operational and obeying well the design-allocated downtime, the first examples of important equipment wear out and/or mishaps were experienced: Damage to the anticryostats Several brakes in case of measuring shafts Loss of several voltage taps integrated with the

current leads Severe wear out (damage) of the 13kA current

lead’s extremities

Silver shoe crisisSilver shoe crisis

Series of actions launched, in particular:

Study of two repair scenarios Procurement of tooling for maintenance and repair Production of additional spare parts

Due to start soon:

Training of ICS operators Change of the installation procedures Procurement of the final tolling for changed

procedures (TS resources required!)

Regular preventive inspection and maintenance of the test benches after at most 10 magnet tests


Conclusions Conclusions Over 2004 all essential equipment was available and operational,

obeying well the design-allocated downtime, in particular this applies to:

Electronics and measuring systems for which the preventive maintenance is in place Powering – even though several significant mishaps Controls and software - even though several developments are not completed

Over the last quarter of 2004 the nominal design test rate for the 12 benches has been established and the max. design test rate has been confirmed

Dedicated S4 equipment (already procured and undergoing procurement) will allow to test in SM18 all types of the Special SSS’s

An economic solution was worked out Major R&D was not needed Most of the technologies and measuring systems were adapted (redeployed)

The silver shoe crisis receives at present particular consideration!

It has drawn attention to the importance of the preventive inspections and maintenance, even if not anticipated by the design
