粒子束光学成像是一种很有前途的距离和宽度估计方法。然而，目前尚不清楚光学成像是否可能用于μ子。为了澄清这一点，我们对μ子进行了光学成像，因为高强度μ子现在可以在J-PARC获得。我们将不同动量的正μ子照射到水或塑料闪烁体块上，并在照射过程中使用电荷耦合器件（CCD）相机成像。水和塑料闪烁体块产生完全不同的图像。水的图像在μ子的照射过程中产生椭圆形的光分布在范围的末端，由于切伦科夫光从正μ子衰变产生的正电子，而对于塑料闪烁体块，我们测量的图像类似的剂量分布。我们能够估计μ子的范围，以及测量的μ子衰变的水的光学图像的正电子发射的方向的不对称性，虽然测量的范围是4毫米至5毫米大于计算值。还可以从塑料闪烁体块的光学图像估计射束的范围和宽度。我们证实了μ子的光学成像是可能的，是一种有前途的方法，质量评估，μ子的研究，以及未来的μ子放射治疗。
Optical imaging of particle beams is a promising method for range and width estimations. However it was not clear that optical imaging was possible for muons. To clarify this, we conducted optical imaging of muons, since high-intensity muons are now available at J-PARC. We irradiated positive muons with different momenta to water or plastic scintillator block, and imaged using a charge-coupled device (CCD) camera during irradiation. The water and plastic scintillator block produced quite different images. The images of water during irradiation of muons produced elliptical shape light distribution at the end of the ranges due to Cherenkov-light from the positrons produced by positive muon decay, while, for the plastic scintillator block, we measured images similar to the dose distributions. We were able to estimate the ranges of muons as well as the measurement of the asymmetry of the direction of the positron emission by the muon decays from the optical images of the water, although the measured ranges were 4 mm to 5 mm larger than the calculated values. The ranges and widths of the beams could also be estimated from the optical images of the plastic scintillator block. We confirmed that optical imaging of muons was possible and is a promising method for the quality assessment, research of muons, and the future muon radiotherapy.
