View source for Far-Forward Tracking and Calorimetry

The Far Forward region consists of four zones:
== Tracker and EMCal in B0 magnet ==
*Approximate acceptance 7<&theta;<20 mrad and |&phi;|<120 deg, with theta relative to the ion beam line
== FFQ magnet string == 
* Cold bore (~20K).  No detectors.  Possible future upgrade with superconducting nano wire trackers, of particular interest for strange baryon decays, ''e.g.'' &Lambda; &rarr; ''p'' &pi;<sup>&minus;</sup>
== Off-Momentum Trackers ==
* RP stations between 25 and 36 m downstream of IP
** AC-LGAD (timing & tracking)
** SiO2 Cherenkov radiator (&delta;Z resolution by signal amplitude &sim;Z<sup>2</sup>)
* Approximate acceptance for 0.45<x<sub>L</sub><0.95
** 0&le; &theta; < 5mrad and (assuming &minus; &pi; < &phi; &le; &pi;)

== Zero Degree Calorimeter (ZDC) ==
* EMCal and HCal,  36-38 m from IP
** Neutron acceptance 0<&theta;<sub>IP</sub> < (6 mrad) &minus; (2 mrad)*cos(&phi;)
== Secondary Focus RP trackers ==
** AC-LGAD and thin SiO2 Cherenkov radiator
** Acceptance (P/Z = 275 GeV, could be different at P/A=41 GeV)
