 1) Comments on the last minutes + Actions

- The minutes were not yet finished... but the actions were clear (http://emetral.web.cern.ch/emetral/LRFF/ListOfActions.htm).

- Concerning our review of equipments with RF fingers (see Action 12), AG asked whether one reviewed equipments form the RF group => I said not for the moment but all the groups were asked to check this. Are there equipments with RF fingers in RF group? (see Action 1 below).

- How to cool ferrite?

- FC is looking to a particular case: spray of ferrite on some conductor => Thin layer.

- One could also take the ferrite and try to attach copper to it. But how? => AlessandroB will have a look to the question: When do we need to start to find alternatives to radiation only and when we need to try and improve the conduction. This means clamping ferrite but risking to break ferrite... This has to be studied in detail. Reminder: the contact impedance depends on the contact pressure and if we have a bad contact pressure we will have an issue.

- We then discussed the agenda of the next meetings as it starts now to become urgent to complete the different actions and conclude this task force => Only 3 working meetings remaining: 30/10, 06/11 and 20/11 (as I will be absent on 13/11). Then I reserved the meeting of 27/11 to show you the slides I could present at the LMC to include all the comments etc.

- On 30/10 => EM (Action 19) + AlessandroB (Action 12) + OK (Actions 5 and 6).

- On 06/11 => MG (Action 1) + OB (Actions 11 and 2) + FC (Action 9).

- On 20/11 (last working meeting) => AlessandroB (Actions 15 and 16) + ?.

- On 27/11 => Wrap-up by EM and draft of the slides to be presented at the LMC.
