| NEWS |
| The technical TTC Web-site has been updated. You will find there news about some problems that have recently been found and fixed as well as other recent information for users of the TTC system. |
| Introduction |
| The TTC system has been developed in the context of the RD12 project. |
| Supported modules |
| The table below lists the types of TTC modules supported: |
| Name | Description / Remarks |
| TTCvi | TTC VMEbus interface module |
| TTCrm | TTCrx mezzanine evaluation board |
| TTCrq | New design of TTCrm with QPLL |
| TTCvx | Low-power VMEbus LED transmitter module |
| TTCex | Primary TTC Laser transmitter |
| TTCtx | Secondary TTC Laser transmitter |
| TTCmx | Primary TTC Laser transmitter for use in TTCmi |
| TTCmi | TTC machine interface |
| TTCoc | optical tree couplers (1:16 and 1:32) |
| Definition of the support |
| The table below specifies which services are available for the individual types of TTC modules. |
| Name | Production | Test | Repair | Technical support |
Electronics Pool |
| TTCvi | Yes | Yes | Yes | Yes | Yes (check availability) |
| TTCrm | Yes | Yes | Yes | Yes | No |
| TTCrq | Yes | Yes | Yes | Yes | No |
| TTCvx | No | Yes | Yes | Yes | Yes (check availability) |
| TTCtx | Yes | Yes | Yes | Yes | No |

| TTCmx | No | Yes | Yes | Yes | No |
| TTCmi | No | Yes | Yes | Yes | No |
| TTCoc | Yes | Yes | Yes | Yes | No |
| Definition of the sub-services | |
| Production | Defines if modules of this type can be (re)produced if required |
| Test | Defines if modules of this type can be tested by PH-ESS |
| Repair | Defines if modules of this type can be repaired |
| Technical support | Defines if an engineer exists who could answer detailed technical questions or fix problems with the design of modules of this type |
| Electronics Pool | Defines if modules of this type can be rented from the CERN Electronics Pool. This service will in any case be limited to short duration rents and the number of modules available will be small |
| Repairs and spares |
| The repair of broken TTC modules will be
carried out on a best effort basis. We do not guarantee that all
modules can be repaired. The time required to repair a module
depends on our workload, the type of the problem and the
availability of spare components.
No ready-to-use spares will be provided by PH-ESS for any of the TTC modules. We recommend that the experiments equip themselves with at least 10% spares. |
| No support is given for: |
| TTCpr, TTCbi, unmounted TTCrx chips | For support of these items please contact their respective designer |
| Optical attenuators | A small stock of 20 db single mode attenuators is still available. Please contact Markus Joos if you want to buy some or if you need the address of a supplier |
| Optical fibers |
Can be purchased from the CERN stores. The SCEMs are:
|
| Modification of existing designs | It is not planned to change the design of any of the supported TTC components. |
| Installation / field services | This service does not include the installation or debugging of TTC modules in any experimental / laboratory setup. |
| Software | This service does not include the distribution of any software for the operation of TTC items. |
| How to obtain TTC modules | |||||||||||||
| All requests for TTC modules have to be authorized by the Electronics Coordinator of the respective experiment: | |||||||||||||
|
|||||||||||||
|
You are therefore asked to address requests for modules of the supported types directly to your Electronics Coordinator who will forward them internally. As the production of additional modules is only possible in batches and subject to contracts there will be deadlines for the submission of requests. The Electronics Coordinators will also decide if modules that have been manufactured for use in the final setup of their Experiment can be used temporarily e.g. for test beams. Once your request for a module has been accepted you will be asked (by means of a TID) to pay the module up-front to a special account reserved for this service. At the same time you will receive a (estimated) delivery date. Once your module has been received you can come and pick it up (usually from 4-R-21). Alternatively it can be shipped to you (at your expense). |
