list of changes

Modificari structura mecanica prototip TRD 2D.docx

• desfacerea moduluilui dupa 1 iulie (RA) [done]
  • inspectie vizuala fara rezultate imediate (Mariana, Laura, Alex) [on going]
• lista modificarilor facute la proiect in urma testelor in casa (Laura) [done]
• HV 
  • de instalat 6 cabluri pe detector (4 x A) + (D + K) cu lungimea cea mai mare pentru a asigura inter-schimbarea detectorilor
  • se va folosi pentru prototip cablul care este in casa (cu folie neagra - desi refuzat la TRD-ALICE) PENTRU ANOD [done]
  •  se vor testa firele HV din casa 
  • trebuie discutata varianta de cabluri pentru D + K !!! si conectica certificata (Cara)[on going]
• Pad-Plane preturi pentru lipirea manuala a flaturilor / camera (Laura, Bugi) 
  • se poate lipi cu letcon cu aliaj de temperatura joasa (~180 grade), fara a se deforma suprafata. Se va face manual, astfel incat timpul aproximativ va fi de 5 lipituri/min (10 ore/pad). Pret (noembrie 2020) 1250/buc fara TVA
  • Trebuie luata o decizie in ceea ce priveste materialul si dimensiunea gaurilor metalizate si daca va fi finisata sau nu ENIG (Electro Nikel Imersion Gold)
• HV box : determinat spatiul ocupat de conectori (Cara) [done] si de construit o macheta (Radu Andrei)
• Fereastra intrare (Laura)
  • we checked all our sources but could not find a supplier for a 20 micron aluminized  PI film- only pure PI films are available. 
  • The aluminized 12 micron  PET Film is also delayed but it is expected to arrive in June and then we are able to cure it with a 100 micron carbon laminate.

3 TRD Frame: simulations discusions

Speaker: Alexandru Bercuci (IFIN-HH)

TRD meeting [LAST]

as discussed in yesterdays TRD meeting, questions on the TRD frame design, in particular to the central part, are to be addressed. 

Propose to dedicate next weeks timeslot Wed 21.06. 14:00 to this subject, *instead* of the general TRD meeting. 

Lukas agreed to have the CAD available live in Zoom. We shall iterate again the available variants, collect questions if so, define neccessary steps/requirements to be worked out still within the preferred variant(s). 
 

4 TRD2D integration mCBM/CBM

• TRD-2D Addendum (publishing status); In-kind (inputs, editors)
• CbmRoot OCT23-Release
• Data analysis mCBM
• Simulation studies for CBM

Speaker: Alexandru Bercuci (IFIN-HH)
