A radiotherapy apparatus includes an acceleration unit configured to generate a charged particle beam. A target is configured to generate a radiation when the charged particle beam is irradiated to the target. A sensor is configured to measure an electric current flowing through the target. A dosimeter is configured to measure a dose of the radiation. A control unit is configured to control the acceleration unit based on the measured electric current and the measured dose.

Radiotherapy apparatus and radiation irradiating method

An acid pickling tank is filled with an acid liquid L, and a lid is attached to the acid pickling tank . A central part of the lid is depressed downwards to form a covering portion . The covering portion is located at a lower position than the liquid level of the acid liquid L in the acid pickling tank to cover a free surface of the acid liquid L. Immersion guide rolls to are provided on the covering portion , support blocks to are provided at the bottom of the acid pickling tank , and skids to are provided on the support blocks to via a bottom plate . Thus, the free surface of the acid liquid L in the acid pickling tank is decreased to suppress a loss of the acid, and prevent an overflow of the acid liquid L to the outside of the tank, thereby making acid pickling of the strip steel plate S efficient.

Pickling device

An acid pickling tank body,is partitioned with a partition wall,into a first tank,and a second tank,. The first tank,and the second tank,are filled with acid liquids L,and L,, respectively, of different concentrations. A lid,is attached to the top of the acid pickling tank body,. On the lid,, immersion guide rolls,to,to,are mounted. On the bottom surface of the first tank,and the second tank,, skids,to,to,are mounted via support blocks,to,to,. A liquid seal,is provided which has a cushion nozzle,for jetting the acid liquids L,and L,toward the surface of a strip steel plate S. traveling above the partition wall,for the first tank,and the second tank

A jet pickling apparatus for pickling the surfaces of continuously moving sheet material (12) has tips of the nozzle headers (41-43) for discharging a pickling fluid (19) on the surfaces of the sheet and into a pickling tank (31) formed into a slit shape (41a-43a), and the nozzles (41,42) at the entrance side are installed to eject pickling fluid in the same direction as the running direction of sheet while the nozzle (43) at the exit side ejects the pickling fluid in the direction opposite to the running direction of the sheet. Therefore, there is no gas in the pickling tank (31) and the tank is filled with the pickling fluid (19), which eliminates the problems of floating of the sheet (12) and insufficient contact of the pickling fluid (19) with the sheet surfaces, allowing thorough pickling and improving the pickling effect.
