Description
The objectives of this meeting are to present and discuss recent results and issues arising since the last progress meeting and to look through progress in writing of our deliverables.
Updates on all activities
Task 1: Layout and optimization of the linac rf system:
-
Showing the distribution of magnetic field on the cells. Needed for thermal simulations by VDL
-
Power dissipation along the structure inlcuding pulse compressor (with the heads and tails of the resulting pulse)
-
Work in progress: calculating more RF parameters
Task 2: Industrialization:
-
Implementing the answers to their questions in their simulations
-
Want to run new simulations and then would like to join the CLIC module meeting in order to exchange on the results and procedures
Task 5: Integration:
-
Nothing much for integration. Just gathering information to work on the WP deliverables
-
Effort for gathering full machine layout info into one place: XML is working fine, but it might not be the optimal solution. We are looking into alternatives again.
Task 4: Power sources for higher-harmonic systems:
-
Article about the design has been accepted for publication
-
Gyroklystron at high repition rate seems feasible (48 GHz might be too difficult, so focus on 36 GHz after meeting with WP3)
-
Work on looking way to compare different frequencies for the linearizer (option of different harmonics)
-
5 potential candidates with general parameters passed to Andrea's simulations
-
Work in progress, but promising on general way of comparing the options. Want to publish this as an article.
-
Maybe we can ask VDL to make a mechanical design for a 36 GHz structure but no full design available just yet (including input coupler design)
Task 3: Modulator technology
-
No news on modulators
News from Gerardo:
-
Amendment: we have contacted the EU and prepared everything.
-
Want to submit only ONE amendment for extension, new WP and new partner.
-
Yesterday submitted all documents
-
Wait for feedback from the EU, but process started.
-
From different sources we believe it is more than likely to have the extension of 12 months because of the pandemic
-
WP4: ask people from CPI to give update with 10MW tube through remote meeting in the next WP4 meeting? - yes, that would be a good idea.
-
BI is WP8 now, but we need some heavy interaction between WP8 and WP4
-
We need to see how this goes
-
Marek to contact CPI to next meeting which Walter will setup right after the meeting
Work on the deliverables:
-
Even with the prespectiver of extension we should go forward and fill in the information on the deliverables we already have
-
Marek shows again the attibution of responsibilities for the chapters
-
Drafts are there and ready to be worked on
-
We use Mendeley for the references as we did in the past.
-
For now only a strong recommendation for putting material in until the next meeting.
