The disclosure is a hollow glass cylinder with an aluminized interior for the reception, temporary retention and study of concentrated solar radiation. The cylinder is toroidal in shape, with an inside wall and an outside wall joined by two end walls. A concentrated beam of high intensity is directed into the cylinder through a rotary light valve, with the line of entry of the beam forming a tangent with the inner surface of the outside cylinder wall. The beam is reflected around the inner surface of the wall, with the direction of propagation at the end of each revolution being parallel to the beam being received through the light valve.
