3 3 10 Feb. '06 - cp PH-ESS LVPS Procurement Wiener Electrical - approved Maraton, F8 & F12 CE conformity (Maraton will be tested by TÜV in March) Magnetic field tolerance 1100 Gauss rather than 1200 Bimetal thermal cut-out changed – to be tested Radiation tolerance - approved TID & SEE (spec: 140Gy over 10 years, 2*10 11 p/cm 2 ) October 2005 Uppsala proton tests showed no effects up to 5.03*10 10 p/cm 2 Probable failure of non-radiation tolerant AC/DC/PFC December 2005 PSI proton tests showed no effects up to 2*10 11 p/cm 2 NIEL (spec: n/cm 2 over 10 years) January 2005 Prospero neutron tests showed no effects up to ~6*10 12 n/cm 2 OPC server Qualified approval for the Maraton (monitoring only over Ethernet) Full F12 functionality over Ethernet (sample end March) Full functionality over Ethernet & CAN (sample two months after approval of F12)

8 8 10 Feb. '06 - cp PH-ESS LVPS Procurement CAEN EASY Electrical Out of spec Power factor EMC Efficiency Noise and ripple CE conformity Need approval by independent laboratory - auto-declaration is insufficient Magnetic field tolerance In spec Gauss Radiation tolerance Tests so far October (PH-ESS) – TSL Uppsala - proton tests showed TID effect and SEE December (PH-ESS) - PSI - proton tests identified particularly sensitive area on boards January (Atlas Muons/CAEN) - Casaccia - gamma tests showed TID effect January (Atlas Muons/CAEN) - TSL Uppsala - proton tests to refine diagnosis and test replacement components also tests of HV boards Planned tests February (PH-ESS) - Prospero - neutron tests end February (PH-ESS) February or March (ATLAS Muons/CAEN) - Pavia - gamma tests on test samples for TID effects March (PH-ESS/CAEN) - PSI - tests on sample boards to verify solution to SEE May (PH-ESS) - TSL Uppsala - final verification (repeat of October tests) OPC server Number of problems identified by IT-CO Solutions promised on March time-scale

9 9 10 Feb. '06 - cp PH-ESS LVPS Procurement CAEN – Electrical issues: actions Power factor The tender calls for a minimum Power Factor of 0.95 (since relaxed to 0.85) The measured value for the A3486 when delivering 3500W was 0.75 With the addition of the harmonic trap (passive filter) a Power Factor >0.9 was measured at 3500W output power and 0.7 at 1730W CAEN will tune the passive filter to cover a wider range of loads, and/or put the two channels in series (two notch filters) Mains harmonic rejection The A3486 was found to be non-conformant to the EN Specification at all loads, however with the addition of the mains filter, the conditions of EN were met at all loads. Use the passive filter (CAEN are not envisaging active power factor correction) Efficiency The specification calls for an overall efficiency (power out/power in) of better than 70% at loads from 10 to 100% of full load The A3486 and A3009 show overall efficiencies of less than 60% at all loads. The A3486 had an efficiency of 88% at an output of 3500W, the A % at maximum possible output (the nominal output was not attainable) - thus giving an overall efficiency of some 58%. PH-ESS showed the major losses to be apparently associated with the transformer (on the A3009). CAEN to investigate further Other parameters On the A3009 measured, the voltage turn-off (fall) was not to specification (5mS) and the current limit could not be tested since it was not possible to reach the nominal output current (~8.8A instead of 9A), also the over-voltage protection did not function as specified (apparently no crow- bar) CAEN are looking to a firmware solution

10 10 10 Feb. '06 - cp PH-ESS LVPS Procurement CAEN – Radiation tolerance: actions Six components identified as sources of problems Pulse width modulator - UCC3580 The UCC3580 will be replaced the non-pin compatible UC3525 (as used successfully in Casaccia and Uppsala on an ATLAS HV board) New versions of the aux DC/DC (CAEN code: DC5) and of the drivers (CAEN code: DRIVXA and DRIVXC) in preparation MOS driver TC4427 – transformer input driver Replacement being proposed (LM5111 or TC4424), has apparently performed well (tests in Uppsala, Week 4) EEPROM - control circuits Pin compatible replacement being proposed. 6 x Schmitt-trigger inverter 74HC14 – general use Components from Fairchild seem particularly sensitive – change to other maker Operational amplifier LM393 used as a comparator Remove completely – redundant monitoring function Opto-couplers HPL0630 – SEEs inducing spurious resets to the microprocessor controller Implement a low-pass filter on the reset line to reduce spikes, demonstrated during tests in Uppsala, Week 4

11 11 10 Feb. '06 - cp PH-ESS LVPS Procurement CAEN – OPC server Hardware persistency (§5.3) Error states in the CAEN HW did not persist across power cycling the HW. Voltage set point not preserved (§5.4) Under investigation – waiting for new OPC Server release. Fault tolerance (§5.5.2) A specific start-up sequence results in incorrect OPC quality values for some of the items. CAEN to retest. Data (Device) Source Access (§5.5.3) The OPC server reads from a cache in the 1527 rather than the Easy modules. Human readable configuration file (§5.5.4) IT-CO to check again. Stability & performance (§5.5.5) Random server crashing. Work in progress Diagnostic Facilities (§5.5.6) Requires a new release of the OPC server. IT-CO (Mark Beharrell) is waiting for the next OPC server release before continuing his tests. Provisional schedule – end-February.
