N1 - Funding Information:
The authors wish to thank the ELPH accelerator staff for stable operation of the accelerators for long-term FOREST experiments. They deeply acknowledge Mr. K. Matsuda for his great technical assistance: the design and construction of the detector frames, and the development of the cryogenic target system. They also express their gratitude to Mr. K. Nanbu for the development of a logic module used for the event tag generator. The authors received a lot of help from many people at every stage of FOREST construction of about five years duration. It is very hard to list completely the persons who could be thanked, but the help of the following persons in particular is gratefully acknowledged: Prof. K. Takamatsu for his invaluable expert advice on electromagnetic calorimeters; Prof. H. Okuno for many helpful suggestions on the INS-type CsI crystals; Prof. M. Taino for his help in finding reusable lead-glass counters at KEK; Dr. T. Yorita and Dr. T. Matsumura for their support in reassembling the Backward Gamma detector. One of the authors (TI) expresses many thanks to Dr. T. Takahashi, Dr. Y. Tajima, and the late Prof. H. Okamura for fruitful discussions on the design work of the data acquisition system. He also deeply thanks Dr. Y. Sugaya for his valuable advice and numerous suggestions on the FERAbus readout. This work was supported in part by the Ministry of Education, Culture, Sports, Science and Technology, Japan as Grants-in-Aid for Scientific Research (B) No. 17340063 , for Specially promoted Research No. 19002003 , for Scientific Research (A) No. 24244022 , and for Scientific Research (C) No. 26400287 .

N2 - An electromagnetic calorimeter complex, FOREST, has been constructed for meson photoproduction experiments at the Research Center for Electron Photon Science, Tohoku University. It consists of three types of calorimeters, which are made of pure cesium-iodide crystals, lead scintillating-fiber modules, and lead glass Cherenkov counters. Each calorimeter is equipped with a plastic scintillator hodoscope to identify charged particles. The design and performance of FOREST are described. The energy responses of test calorimeters have been investigated by using 100–800 MeV positron beams. The energy resolutions of the three calorimeters are found to be approximately 3%, 7%, and 5% for 1-GeV photons, respectively. A cryogenic hydrogen/deuterium target system fitted to the FOREST experiments and a newly developed data acquisition system are also presented.
