In December 1987 a Workshop was held in Courmay-cur (Italy) on ''Heavy-Quark Factory and Nuclear-Physics Facility with Superconducting Linacs''. In this paper the authors summarize and update the main machine points discussed in detail in the Proceedings of the workshop. The facility proposed by the authors is schematically shown in Figure 1 which is taken from Ref. [3]. The ''SC radiofrequency complex'' is a recirculated superconducting electron and positron linac which serves as a b{bar b} factory and a high-duty cycle nuclear physics facility. It can provide electron-positron collisions in the c.m. energy range 10 {le} W {le} 20 GeV with luminosities L {le} 10{sup 34} cm{sup -2} s{sup -1} and, at the same time, high intensity and large duty cycle electron beams for nuclear physics experiments up to about 10 GeV. The scheme of Figure 1 consists of two racetrack linacs, each one being similar to the CEBAF design [4]. It offers also the possibility of producing c{bar c} (quarks) for 3 {le} W {le} 4 GeV with L > 10{sup 32} cm{sup -2} s{sup -1} and of colliding 2.5 Gev positrons (extracted from the damping ring) with 11.2 GeV electrons, so as to produce moving {Upsilon}(4S) states and have an easier access to the study of CP violation. The main parameters for the b{bar b} factory are collected in Table 1. For nuclear physics the CW beam has a current {le} 200 {micro}A and a duty cycle {ge} 80%.
