Agenda

  • Answer to PAC reviewer questions Overleaf link (please require access to Dipangkar):
  1. How has the TDIS collaboration evolved since this experiment was first proposed to today? Have there been any significant changes to the number of institutions, staff, or prospective students?
  2. Could you please say more about the needs and plans for the additional 33 days of operations? Specifically:
  3. For the 13 day engineering run, it is understood that the beam luminosity will be increased in stages. How many days of running are needed at each stage? How will the optimal luminosity be determined? For the additional 20 days of running to support pion and kaon SF measurements, how was the duration of 20 days arrived at? What improvement in physics measurement capability is expected with 20 additional days of data-taking? Is it possible to couple this additional 20 days to a quantitative measure of added physics performance?
  4. The detector redesign and associated prototyping effort that has taken place since the experiment was first proposed is both impressive and important. What is the approximate expected timeline for obtaining results from the two detector prototypes? The first detector prototype will take data in Hall A at JLAB and at Fermilab this fall: what about the second prototype? When is it expected to be operated and where? Could you please comment on roughly when you expect to have results from this full complement of detector prototypes?
  5. We note that the previous PAC commented that the choice of a 4.7 T solenoid magnetic field may not be optimal for the lowest momenta recoil protons. How has this been addressed? Has the performance for low momenta protons in this B field been studied in simulation?
  6. It is mentioned in the update that new developments in TDIS theory since 2015 have resulted in an expected increase in the TDIS signal yield. Could you please give a rough sense of how much larger a signa rate is expected based on these new developments?
