[BTeam] Minutes from Yesterday

[Mike Spata]

Colleagues, 

I updated the wiki page with the minutes (https://accwiki.acc.jlab.org/do/view/BTeam/BTeam20170124). 

Also echoed here: 



Minutes 

    * Alexandre Duer presented the 8-week run plan for Hall D (slides on wiki) 
        * Main points of discussion: 
            * Asking for 1 nA - 1.5 μA with production running at 200 nA. 
            * FFB and slow locks ON. 
            * Tagger quadrupole at -4.2 A for Hodoscope tune. 
            * Collimator at 5.0 mm for most of run. 
            * Final focus needs to be on the collimator. Last run the waist was at the radiator because of background issues. 
    * Start-up discussion: 
        * Injector beam is matched to inline dump with 10 μA CW run from 3 lasers. 
        * First beam into NL on Wednesday swing. 
        * Machine tuning will start with eDT download and follow ORFP. Match at all arcs. 
        * Third pass beam will be extracted (RF) to Hall B dumplet and matched for upcoming KPP runs to Halls B and C. 
        * Jay is Optics-on-call for first week. Control room support for the spin-up: 
            * Thursday Michael 
            * Friday Yves 
            * Saturday Todd 
            * Sunday Mike 
        * 750 MHz commissioning scheduled for Sunday day/swing. 
        * Hall D final setup on Monday 
        * Hall B 3rd pass tune-up 2/1-2/3 with KPP demo to follow setup. 
        * Hall C 3rd pass tune-up 3/7-3/9 with KPP demo to follow setup. 
        * Hall A opportunistic run at 1st pass starting on 2/17. 
        * Hall C wants 5th pass beam starting on 3/16. 
        * Run ends on 3/23. 
        * Joe mentioned that Hall C laser needs to be switched to 250 MHz if the 5th pass run during the last week happens. 
        * Michael mentioned that we need to validate multi-hall optics solution for 3-way vertical split at high energy.
