Hi Or,

         Thanks for bringing up this import point. Yes, we will consider the costs for sure. The starting point is to check the impacts of a DIRC with different radius (if we can afford the cost 😊), then we optimize and merge different detector design/layout into a whole system considering the integration, cost, risk and etc.

          Further suggestions and comments are very welcome!

         Thanks.

Hi,

Thanks for all for the great work and very encouraging results :)

I have a question about the statement on “Look into tuning the DIRC radiuses”. I think that from a cost and risk point of view there is a strong desire to propose re-using the existing DIRC bars from BaBar. In that sense, I think it would be good to always keep that as a reference size so that if one optimizes a DIRC radius we present the improvement of the different radius compared with the ‘free’ (/less expensive) solution and can make an informed cost/performance balance.

Thanks,

Or

Hi All,

        Thanks for joining today's ECCE tracking WG meeting and we has very productive discussions today. The meeting minutes have been posted to the indico agenda below:

        You could see the meeting minutes for today below:

1, forward silicon tracker by Ping (LANL):

Presented the yellow report results and new studies for barrel Si + FST, barrel Si + TPC + FST and DIRC + barrel Si + FST geometries. Summarized material budgets for different detector combination and tracking performance for the barrel Si + TPC + FST. These performance have been implemented into the HF reconstruction and ReA projection.  

Suggested to compare different detector designs/technologies.

2, EIC Tracking and PID studies by Rey (LBNL) and Wenqing (LBNl):

Rey presented Hybrid design of Si+GEM in the barrel and endcap regions. Improvement in the momentum resolution can be done with the Si+GEM hybrid design. Look into tuning the DIRC radiuses to check the impact on the tracking.

Wenqing presented PID detector options and start the Toy MC studies specifically associated with a LGAD based ToF in the barrel region. Have achieved the ToF perofmrnace for 3sigma PID for pi, K, p. Compared the p reach between Babar and Beast magnets and compare the requirements on the time and path length resolutions with R locations and magnet options.

Suggest to give the presentation in the ECCE PID WG meeting and take into account of the physics requirements. For PID, suggested to look into the electron PID as well.

3, general suggestion:

We need to provide the cost and schedule in the detector proposal. We would like to get the information from expert of the proposed detector technology.

We briefly discuss about the LGAD cost and will keep work on it and the other detector technologies.

       Talk to you next Friday morning.

       Thanks.
