The connection support device includes a rod-shaped member insertable into respective hollow portions of two or more cell structures, the rod-shaped member being inserted into the hollow portions, the rod-shaped member including a circular cross section having an outer diameter capable of adhering to inner surfaces of the cell structures when the rod-shaped member contracts after maturing, and a total length longer than a sum of respective lengths of the two or more cell structures, and two presser devices including clamp portions capable of being fixed to the rod-shaped member by clamping and fitting to the rod-shaped member, the rod-shaped member being made of a material with oxygen permeability.

Cell structure connection method and connection support device

The cell structure producing apparatus including needles, a sticking unit configured to detachably hold an end portion of each of the needles, descend the each of the needles with respect to a cell tray in which cell aggregates are held, stick and penetrate each of the cell aggregates with the tip end, and ascend the needle after sticking, at least one time or more, a base unit, and a control unit configured to move the sticking unit so that for the each of the needles, each of the needles sticking the cell aggregates is positioned at a predetermined position over the base unit, descend each of the needles by a predetermined amount to stick the tip end into the base unit at the predetermined position on the base unit, and control the sticking unit.

A dose distribution calculation device of the invention is characterized by including: a beam information storing unit (a measured energy storing unit, a measured electric-charge storing unit, a measured beam-central axis storing unit), in which, when particle beam information of a particle beam generated by a particle beam therapy system is measured by a measuring device in confirmative radiation in which the particle beam is radiated to a phantom as a substitute for a treatment target, the thus-measured particle beam information is stored; and a total dose calculation unit for calculating a radiation dose distribution (a total dose distribution) on the basis of the measured particle beam information (a measured energy, a measured beam quantity (a measured number of electric charges), a measured position of beam central axis).

A method of manufacturing a radio frequency accelerator that accelerates charged particles injected into a second-stage linear accelerator from a first-stage linear accelerator includes a step of setting a value of a power distribution factor R for the power distributor to supply radio frequency power to the second-stage linear accelerator and a value of a ratio L/&#x3c9; of a length L of the matching section between the outlet of the first-stage linear accelerator and the inlet of the second-stage linear accelerator to the angular frequency &#x3c9; of the radio frequency power, so that a charged particle beam is extracted from the second-stage linear accelerator over a range of the total radio frequency power wider than a widest allowable range among allowable total radio frequency power ranges determined for each phase of charged particles on the basis of phase acceptance of the second-stage accelerator.
